description

This O-ring is molded from EPDM rubber with 70A hardness, featuring good resistance to hot water, glycol coolant and ozone aging. It is designed for static sealing on cooler, pipe joint and thermostat housing. Thermal aging, cut damage and weakened rebound will trigger water seepage and air intake, leading to unstable engine temperature and overheat failure.

FAQ 

Q：Can whitened O-ring without crack be reused?
A：Not recommended. Whitening means aging and elasticity loss, leakage may occur under temperature cycle.

Q：Can this EPDM ring seal hydraulic oil or diesel?
A：No. EPDM is incompatible with mineral oil and will swell rapidly.

Q：What will happen if ordinary grease is used for lubrication?
A：Mineral oil attacks EPDM and causes swelling and coolant leakage.

Q：Does leakage after new seal installation mean defective O-ring?
A：Check flange corrosion and groove deformation first, damaged mating face cannot be fixed by seal replacement.
