Petromax · Lamp replacement part
Rapid preheater HK350/HK500: complete assembly in brass or chrome The preassembled Petromax Rapid preheater is designed for HK350/HK500 and is offered as a complete unit. This is the right solution if not just a single Rapid component but the entire assembly needs to be replaced.
Important before purchase: Brass and chrome are variants of the same function. Choose the version matching your existing lantern; according to Shopify data, this item is not listed for HK150/HK250.

Fits well / fits less well


Fits well if … … the Rapid preheater on your HK350/HK500 should be renewed as an assembly or multiple components are worn out.


Fits less well if … … clearly only the gasket, nozzle, toggle lever, or another single small part is defective.


Features with practical impact


Preassembled unit The existing product data lists eight individual parts in one assembled assembly. This reduces the number of separate components that need to be sourced individually.


HK350/HK500 The model assignment is decisive for purchase. Check the lamp model on your own unit before ordering.


Brass Functionally the same assembly in brass finish – useful for corresponding lantern versions.


Chrome The chrome-plated version visually matches silver-colored or chrome HK350/HK500 versions.


Limits, disadvantages & avoiding wrong purchases

A complete Rapid preheater is not automatically the most economical choice if only a clearly identified small part is defective.
A new assembly also does not fix errors outside the Rapid system, such as insufficient tank pressure or other leaks.

Black Raptor · Buying advice
The right choice for a genuine assembly replacement. If only a small Rapid part is defective, targeted individual part replacement is usually more sensible.
