Finish Thompson J102774 Viton Housing O-Ring
This is the factory viton housing o-ring for Finish Thompson KC11 magnetic drive pumps. It seals the KC11 housing where the wet end is closed up, and it is the only gasket holding that joint. It is built in Viton FKM fluoroelastomer, which is what decides where it can safely be used.
It is one of the parts worth renewing on schedule instead of waiting for a fault. It is disturbed every time the pump is opened, and a ring that has taken a set will start a hairline weep even though it looks perfectly sound. Check the pump build before ordering, because these pumps are offered in more than one material and size combination and the alternatives look similar on the shelf.

Frequently Asked Questions
Q: Does a replacement ring need a torque check afterward?
The fasteners should be drawn down evenly in a cross pattern, then rechecked after the first run once the joint has settled.
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.
