This Petromax steel washer completes the handwheel assembly of an HK150, HK250, HK350, or HK500. It is delivered as a single original spare part without marking and is intended for the targeted replacement of a missing or damaged washer. Handwheel, handwheel nut, and eccentric are not included.

for Petromax HK150, HK250, HK350, and HK500
Original single part for the handwheel area
unmarked version without stamping
made of steel, weight 2 g
not a complete handwheel or eccentric replacement



What is this washer?
The washer is a single small part from the operating area of the Petromax pressure lamp. Petromax assigns it to the handwheel and lists it in the spare parts overview as part no. 227. According to the manufacturer, it fits all four lamp models HK150, HK250, HK350, and HK500.
Its clear manufacturer description is "washer without marking." No further sealing, bearing, or friction function is publicly specified. Therefore, the washer is not presented here as a universal repair for a stiff handwheel or leaking lamp parts.

Product classification: Class: single original small part of the handwheel assembly. Directly usable: only together with the existing, matching handwheel and eccentric parts. System environment: handwheel → washer → handwheel nut or adjacent eccentric assembly. Important: installation position and order must be confirmed based on the existing assembly or exploded view.
When is buying the single part useful?
During maintenance and restoration, the handwheel and adjacent small parts are often disassembled. The small washer can be lost, bent, or already missing in an incomplete lamp. If the assembly is otherwise intact and clearly identified, it can be specifically completed with the single part without replacing the handwheel or eccentric completely.
For an unknown, heavily modified, or assembled from multiple lamps assembly, the model designation alone is not sufficient. Then the exploded view, existing nut, handwheel, and eccentric should be checked together. A visually similar hardware store washer is not a reliable replacement because Petromax does not provide public detailed dimensions or tolerances for the single part.
Scope of delivery and technical distinction
1 × Petromax washer for the handwheel, unmarked version
Not included: handwheel, nut, eccentric, eccentric shaft, eccentric nipple, locknut, gasket, or tools.
The original part is made of steel and weighs 2 g according to the manufacturer. It is not a gasket and is not offered by Petromax as a component to fix tank or carburetor pressure loss. In such cases, the actual pressure-bearing connections and seals must be checked.
Correctly narrowing down handwheel faults
If the washer is visibly missing, the assignment is clear. However, if the handwheel turns stiffly, has excessive play, or does not move the mechanism as intended, handwheel nut, eccentric shaft, eccen
ternippel or the complete eccentric assembly may be affected. Replacing a single small part on suspicion does not replace this diagnosis.
Before working on the lamp, it must be completely cold and depressurized. The Petromax manual also requires the use of suitable original spare parts and a check of the functionally relevant assemblies before the next commissioning.
Practical tips for maintenance and restoration

Document disassembly order Photograph the handwheel, nut, and visible small parts from a short distance before disassembly. For a washer without embossing, the documented order helps more than later comparing similarly looking individual parts.

Do not discard old parts prematurely Keep a damaged or bent original washer until the repair is complete. It serves as a reference for position, diameter, and assignment to the other components.

Do not use just any washer Outer and inner diameter alone are not enough: thickness and material also affect the assembly. Without confirmed dimensions, a standard washer must not be assumed to be equivalent.

Check the system if stiff If operation remains noticeable after correct completion, check the handwheel nut, eccentric nipple, shaft, and eccentric for wear or misalignment. Additional force on the handwheel can further damage plastic and mechanics.

Black-Raptor short summary: Buy if: the unmarked original washer is missing in a clearly assigned handwheel assembly of the HK150 to HK500. Do not buy if: a complete handwheel, an eccentric, or a seal is needed or the cause of the malfunction is still unclear.

Suitable parts of the handwheel and eccentric assembly:
Petromax handwheel blue HK150–HK500
Petromax nut for the handwheel
Petromax eccentric complete HK150–HK500
Petromax locknut for the eccentric

Is the handwheel nut included? No. Only the single steel washer is delivered.
Does the washer fix a leaking system? No. It is not considered a seal. In case of pressure loss, the pressure-bearing components and seals must be checked separately.
