Finish Thompson J102775 EPDM Housing O-Ring
Finish Thompson supplies the J102775 as the epdm housing o-ring for KC11 magnetic drive pumps. It is the EPDM housing seal for the KC11, specified where the pumped fluid attacks fluoroelastomers. It is built in EPDM, which is what decides where it can safely be used.
Most pumps see this part replaced well before the pump itself needs attention. EPDM is not suited to petroleum oils or most hydrocarbon solvents, so a pump that changes duty may need to go back to the standard ring. Confirm the material and size against your pump before ordering, as the same position is offered in several variants across this range.

Frequently Asked Questions
Q: What does a flattened cross section mean?
It is compression set, and it tells you the ring has given up the elastic recovery that keeps a joint tight through heat cycles.
Q: Should the mating groove be cleaned before fitting?
Yes. Old elastomer residue or dried product in the groove stops the new ring seating flat and is a common cause of a repeat weep.
Q: Can the ring be stretched over a housing to fit it?
A small amount of stretch is normal during assembly, but it should relax back into the groove before the joint is drawn together.
Q: How should spare rings be stored?
Cool, dark and away from electric motors, because sunlight and ozone age rubber long before it ever reaches the pump.
