Fire Extinguisher Spare Parts List for Assembly Plants
This spare parts list covers the components an assembly plant needs to build and service ABC dry powder extinguishers from 1 kg to 50 kg: cylinders, valves, hoses, nozzles, gauges, handles, powder and brackets. The practical benefit is fewer mismatched parts, predictable container loading and a clear basis for request an FOB quotation.
Which spare parts do you need to assemble a complete ABC dry powder extinguisher?
A complete unit is built from six functional groups. Ordering by group prevents shortages at the filling line.
| Group | Parts | Typical materials | Notes for buyers |
|---|---|---|---|
| Cylinder | Body, neck ring, base ring | Carbon steel, powder-coated red | State test pressure and wall thickness |
| Valve assembly | Brass valve body, safety pin, lever, spring | Brass, stainless steel | Confirm thread standard before ordering |
| Discharge | Hose, nozzle, siphon tube | Rubber or PVC hose, plastic or brass nozzle | Hose length varies by cylinder size |
| Pressure indication | Gauge, color-coded dial | Brass or steel case | Check gauge thread and range |
| Carry and mount | Handle, bracket, strap | Steel, plastic | Bracket type depends on wall or floor mounting |
| Agent and label | ABC dry powder, label, tamper seal | MAP-based powder | Specify MAP percentage and labeling language |
For a finished reference unit, see the 8kg ABC Dry Powder Fire Extinguisher.
What are the filled weight, gross weight and 20ft container loading for each size?
Container loading depends on carton size and gross weight, not on nominal capacity. The table below gives planning ranges for standard cartons; confirm final figures on the packing list before booking.
| Nominal size | Filled weight (approx.) | Gross weight per carton (approx.) | Units per 20ft (planning range) |
|---|---|---|---|
| 1 kg | 1.6–2.0 kg | 2.0–2.5 kg | 6,000–8,000 |
| 4 kg | 6.0–7.0 kg | 7.0–8.0 kg | 2,200–2,800 |
| 8 kg | 11.5–13.0 kg | 13.0–14.5 kg | 1,100–1,400 |
| 12 kg | 17.0–19.0 kg | 18.5–20.5 kg | 750–950 |
| 50 kg | 68–75 kg | Trolley or pallet | By pallet, check with supplier |
For Indonesian assembly plants, carton dimensions and pallet patterns matter as much as weight, because mixed containers are common. Ask for a loading plan with the quotation.
Which cylinder specification should you specify: pressure, steel grade and wall thickness?
Specify working pressure, test pressure, steel grade and wall thickness together, because they determine the valve thread and the safety margin. Typical ABC dry powder cylinders use working pressure around 14–15 bar and test pressure around 25–27 bar, with carbon steel bodies and wall thickness that varies by diameter. Do not accept a verbal figure: request the drawing and the pressure test record for the batch.
Pressure vessel approval: TPED, DOT or local rules?
For Europe, ask for TPED compliance evidence; for the United States, DOT approval applies to the cylinder. For Indonesia and most ASEAN markets, local regulation and buyer specification usually govern, and importers should confirm with their authority. A supplier should state which directive it complies with and provide the supporting documents, not just a claim.
What powder composition and MAP percentage should the spare parts order include?
ABC dry powder is normally based on monoammonium phosphate (MAP). Many buyers specify a minimum MAP content of 75% for A and B rating performance; lower-cost blends may reduce MAP and add fillers. Ask for the batch certificate of analysis showing MAP percentage, moisture and flowability, and confirm the fire rating achieved in testing for the size you assemble. Ratings are size-specific, so the 8 kg result does not automatically apply to the 1 kg unit.
How should you handle certification and test reports for export?
Treat certification as a document set, not a single certificate. Request the EN 3 test report from a notified body where applicable, the CE declaration, the pressure vessel approval, and the powder analysis. Verify the certificate number with the issuing body rather than relying on a scanned copy. If a supplier cannot name the issuing laboratory, treat the claim as unverified.
What MOQ and FOB price structure should you expect for 500, 1,000 and 3,000 units?
MOQ and price depend on size, private label and packaging. As a planning rule, expect unit price to fall as volume rises from 500 to 1,000 to 3,000 units, and expect private label to add a setup cost. Ask for a price table by size and quantity, FOB Ningbo or Shanghai, with packing included and payment terms stated. Because prices move with steel, brass and freight, request a validity period.
Can you supply private label, and what is the lead time?
Private label is normally feasible: your brand on the label, carton design and manual. Lead time depends on artwork approval, label printing and production scheduling; a common planning window is several weeks after deposit and artwork sign-off, longer for large or multi-size orders. Keep the label text compliant with the destination market and confirm the language before printing.
What shelf life, service interval and gauge readability should you verify?
Dry powder is typically given a shelf life of several years in a sealed cylinder, and service intervals follow local rules, commonly annual inspection. The gauge should have a clear color-coded dial with the needle in the green zone at normal pressure, readable at arm's length. Check gauge thread compatibility with your valve stock.
What warranty and defect policy should the contract state?
The contract should state the warranty period, what counts as a defect, and the remedy: replacement, credit or repair. Agree on the inspection method at arrival, the claim window and who pays freight for replacement parts. For assembly plants, a spare-parts allowance in the first shipment often resolves small defects faster than a claim process.
Common mistakes in spare parts procurement
- Ordering valves without confirming thread standard against cylinder stock.
- Assuming one fire rating applies to every size in the range.
- Accepting a certificate copy without verifying the issuing body.
- Ignoring carton dimensions when planning a 20ft container.
- Printing private label artwork before regulatory text is approved.
- Leaving warranty, claim window and replacement freight out of the contract.

FAQ
What is the exact filled weight and gross weight per unit, and how many units fit in a 20ft container?
Filled and gross weight vary by size and carton, so treat published figures as planning ranges and confirm them on the packing list. An 8 kg unit is typically around 11.5–13 kg filled, with a carton gross weight near 13–14.5 kg. A 20ft container commonly holds roughly 1,100–1,400 units of 8 kg in standard cartons. Smaller sizes load far more units, while 50 kg trolley units are usually shipped by pallet. Ask for a loading plan with carton dimensions before booking space.
Is the extinguisher certified to EN 3, and can you provide the CE certificate and test report from a notified body?
EN 3 compliance must be supported by documents, not a claim. Ask for the EN 3 test report from a notified body, the CE declaration and the pressure vessel approval, and verify the certificate number with the issuing body. If a supplier cannot name the laboratory or the notified body, treat the certification as unverified. Confirm which sizes are covered, because reports are size-specific. Keep copies with your import file for customs and for your own customers.
What is the ABC dry powder composition and percentage of monoammonium phosphate, and does it meet the minimum 75% MAP requirement?
ABC dry powder is normally based on monoammonium phosphate, and many buyers specify a minimum of 75% MAP for A and B performance. Ask for the batch certificate of analysis showing MAP percentage, moisture content and flowability. Lower-cost blends may reduce MAP and add fillers, which can affect rating performance. Specify the minimum percentage in your purchase order and require the certificate with each shipment, so the specification is enforceable rather than assumed.
What is the fire rating (A and B) achieved in testing, and can you send the test report showing the rating for the 8kg size?
Fire ratings are size-specific, so request the test report for the exact 8 kg unit you assemble. The report should show the A and B rating achieved, the test method and the laboratory. Do not apply the 8 kg result to 1 kg or 4 kg units without separate evidence. Keep the report with your technical file and quote the rating on the label only as supported by that report.
What is the working pressure and test pressure of the cylinder, and what steel grade and wall thickness do you use?
Typical ABC dry powder cylinders use a working pressure around 14–15 bar and a test pressure around 25–27 bar, with carbon steel bodies. Wall thickness depends on cylinder diameter and design, so request the drawing and the pressure test record for the batch rather than a single figure. Confirm the steel grade, the valve thread and the coating specification together, because these determine compatibility with your valve and hose stock.
Does the cylinder have a TPED or DOT approval, and which pressure vessel directive do you comply with for export to Europe or the US?
TPED applies to cylinders exported to Europe and DOT approval applies to the United States, so the answer depends on the destination. Ask the supplier to state in writing which directive it complies with and to provide the supporting approval documents. For Indonesia and other ASEAN markets, local regulation and buyer specification usually govern, so confirm with your authority. A supplier that cannot name the directive and show documents should not be treated as approved.
What is the MOQ, and what is the price per unit for 500, 1000 and 3000 units FOB Ningbo or Shanghai?
MOQ and price depend on size, private label and packaging, so ask for a price table by size and quantity at 500, 1,000 and 3,000 units, FOB Ningbo or Shanghai. Expect unit price to fall as volume rises and private label to add a setup cost. Request the validity period, packing terms and payment terms with the table, because steel, brass and freight prices move. Compare offers on the same specification and Incoterm.
Can you supply the extinguisher with our own brand, label and carton design, and what is the lead time for private label production?
Private label is normally feasible, covering your brand on the label, carton design and manual. Lead time depends on artwork approval, label printing and production scheduling; a common planning window is several weeks after deposit and artwork sign-off, longer for large or multi-size orders. Approve regulatory text for the destination market before printing. Confirm minimum order quantity per size, because small quantities per size can raise the setup cost.
What is the shelf life and service interval of the dry powder, and does the gauge have a color-coded pressure indicator that is easy to read?
Dry powder in a sealed cylinder is typically given a shelf life of several years, and service intervals follow local rules, commonly annual inspection. The gauge should have a clear color-coded dial with the needle in the green zone at normal pressure and should be readable at arm's length. Check the gauge thread against your valve stock before ordering. Confirm the shelf life statement and service guidance in the manual for your market.
What is your warranty and defect policy, and how do you handle replacement or compensation if units fail inspection on arrival?
The contract should state the warranty period, what counts as a defect, and the remedy: replacement, credit or repair. Agree on the inspection method at arrival, the claim window and who pays freight for replacement parts. For assembly plants, a spare-parts allowance in the first shipment often resolves small defects faster than a formal claim. Put all of this in the purchase order, not only in email, so it is enforceable.
