Burks 23000 Viton Gasket Ring 162 mm ID
This is the Viton gasket ring Burks specifies as part 23000, 162 mm inside diameter. Its job is simple and unforgiving - hold pressure at a joint that has to come apart again for service.
Elastomer seals age whether the pump runs or not. Heat and the pumped liquid slowly harden the compound, the ring takes a permanent set in the shape of its groove, and it stops springing back when the joint is opened. A ring that has gone hard and flat will usually seal again once, and then weep a few days later under pressure cycling. That is why it is standard practice to fit a new one every time the joint is broken.
Material is the part of this number that matters most. Viton is what Burks fitted here, and swapping compounds changes what the pump can safely handle - temperature range, and which liquids will attack the seal. Burks lists the same physical size in several compounds for exactly that reason, so match the material as well as the dimension.

Frequently Asked Questions
Q: How should these be stored?
Cool, dark and dry, away from ozone sources such as electric motors, and not stretched over a hook. Elastomers age on the shelf, so rotate stock rather than keeping one ring for a decade.
Q: How can I tell whether a leak is this seal or the shaft seal?
A static joint seal weeps along the split line between two castings and does not change with shaft rotation. A failing mechanical seal usually drips from underneath the adapter behind the casing and often gets worse as the pump runs and warms up.
Q: Should I lubricate the ring before fitting it?
A light smear of a grease compatible with the ring compound helps it seat and stops it rolling or pinching as the joint closes. Avoid petroleum grease on EPDM, and avoid anything that will contaminate the liquid you are pumping.
Q: The old ring looks fine. Can I reuse it?
It is not worth it. A ring that has been under compression has already taken some set, and the cost of a repeat teardown is far higher than the ring. Seals of this type are treated as single-use items across the industry.
