Burks 23005 EPDM Gasket Ring 200 mm ID
This is the EPDM gasket ring Burks specifies as part 23005, 200 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.
Burks supplies this size in more than one compound, so the material is part of the part number, not an option. EPDM here sets the service temperature and the range of liquids the joint will tolerate. Fitting the same size in the wrong compound is one of the more common causes of a seal that fails within weeks.

Frequently Asked Questions
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.
Q: What tightening sequence should I use on the joint?
Draw the fasteners down evenly in a cross pattern in two or three passes rather than pulling one side home first. Uneven closing is what pinches a ring and leaves it nicked on one edge.
Q: Can I use a generic ring from a seal kit instead?
A generic ring in the same nominal size will often sit in the groove, but the compound, the shore hardness and the cross section tolerance are what Burks specified. Those details decide whether it seals for years or seeps in a month.
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.
