Water Jacket O-Ring 1.5x19.5 for G230PUM - Zenoah K116012320  [K116012320]

G230PUM cooling seal details

The Zenoah K116012320 O-ring is produced to the 1.5x19.5 mm specification for direct use with the G230PUM water jacket connection. It is designed as the sealing component for the cooling jacket area on compatible G230PUM engines used in RC models.

Fit this O-ring when existing seals are brittle, cut, or distorted and allow coolant to escape. The item is dispatched without extra packaging; check the K116012320 identifier and the 1.5x19.5 stamp before you fit it.

Fitting recommendations:

• Thoroughly clean the mating surfaces and clear any old adhesive or debris from the groove.
• Inspect for groove imperfections or corrosion that could stop the O-ring from sealing properly.
• Use a light smear of the manufacturer's recommended lubricant on the O-ring to prevent damage while seating.
• Reassemble parts in an even sequence to ensure uniform compression on the O-ring and run a low-speed leak check prior to heavy use.
