Finish Thompson J101085 Viton Housing O-Ring
This is the factory viton housing o-ring for Finish Thompson GP22, GP32, KC22 and KC32 pumps. It seals the main housing joint on the larger GP and KC pumps, holding in everything the pump develops. 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 takes a compression set against its groove, so it should be renewed at every teardown rather than reused because it still looks round. 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: 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.
Q: Is a lubricant needed on assembly?
Only one known to suit the pumped chemical, and only a trace. The wrong grease can swell the ring as badly as the wrong elastomer.
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.
