Replacement seal for cooling passages

This is a water jacket O-ring intended to restore the sealing surface on Zenoah small gas engines. The component corresponds to the 3x40 size listed in the product name and is supplied without additional packing.

Use this O-ring when you service the cooling passages on compatible Zenoah models, and thoroughly check the jacket bore and mating faces for contamination before fitting. Ensuring a clean contact surface and correct seating will minimise leak potential and make maintenance quicker.

Fitting guidance: remove any remnants of the old seal, examine the groove for nicks or burrs, lightly lubricate with a product safe for rubber seals to aid placement if necessary, and confirm the ring sits evenly around the jacket before reassembling the engine.

Compatibility

  • G231PUM
  • G260PUM

How do I confirm compatibility with my engine model?

Check that your engine is listed among the compatible models and that the water jacket bore matches the 3x40 specification. If the bore or mating face has been modified, verify dimensions before fitting the O-ring.

What inspection should I do after fitting the new O-ring?

After assembly, run a brief pressure or leak check where possible and visually inspect for any seepage at the jacket joint. If any seepage appears, re-open, reseat the ring, and recheck the mating surfaces.

Is there a recommended routine for replacing this part?

Replace the O-ring during scheduled engine overhauls or sooner if you detect hardening, cracking, or persistent leaks. Regular inspection at service intervals will reduce the risk of cooling failures.
