Service O-ring for water jacket

This RC water jacket O-ring is designed to restore the sealing surface on Zenoah small gas engines. The item matches the 3x40 size indicated in the product title and is supplied without extra packaging.

Fit this O-ring when you are servicing the cooling passages on compatible Zenoah engines, and check the water jacket bore and mating surfaces for dirt or damage before installation. Correct seating and a clean contact surface help reduce the chance of leaks and speed routine maintenance.

Installation tips: clear away old seal material, inspect the groove for nicks, apply a light film of a suitable oil to ease placement if required, and ensure the ring sits evenly around the jacket prior to reassembly.

Compatibility

  • G231PUM
  • G260PUM

How can I verify the O-ring fits before final assembly?

Place the O-ring into the water jacket groove and rotate the jacket slowly by hand to confirm even seating. Look for any gaps, twists, or pinched areas and adjust as needed before tightening components.

When is it time to replace this seal?

Replace the O-ring if you notice hardening, visible cracks, or ongoing seepage after reassembly, or include it as part of scheduled engine servicing to avoid unexpected leaks.

Any precautions during installation?

Thoroughly clean mating surfaces, avoid overstretching the O-ring, and remove any debris from cooling passages before you run the engine to prevent damage and leaks.
