When it may not be suitable
This component is exclusively designed for the specified Petromax models and is not compatible with other brands of pressure lamps or different series of Petromax lanterns. It should not be used if the threads on the control spindle itself are damaged, as the nut will not be able to secure the knob properly.
Key specifications
Compatibility: Petromax HK150, HK250, and HK300
Function: Secures the control knob to the spindle
Material: Heat-resistant metal construction
How to use
To install the nut, first ensure the lamp is completely cool and depressurized. Remove the existing damaged nut if present. Align the control knob onto the spindle and thread the Dymo nut onto the spindle shaft by hand. Tighten it gently until the knob is held firmly in place, taking care not to overtighten, which could damage the threads.
What to consider before purchase
Verify your lamp model is HK150, HK250, or HK300
Check the condition of the spindle threads before installation
Ensure you have the correct tools for lamp disassembly if required
Usage recommendations
Regularly inspect the control knob assembly during routine maintenance to ensure the nut remains tight, as vibrations during transport or operation may cause it to loosen over time.
