Oberdorfer 9237 Gasket – PTFE Replacement Part
This is the genuine Oberdorfer 9237 gasket, made in PTFE. Gaskets are consumables in the strictest sense: they are crushed to seal, and once crushed they cannot be relied on a second time.
Heat, pressure cycling and chemical attack all age a gasket in place. On a pump in seasonal service, the lay-up is often harder on the gasket than the running hours are.
Clean both faces completely, fit dry unless the manual says otherwise, and tighten the fasteners evenly in a cross pattern to the specified torque.

Frequently Asked Questions
Q: Can I cut my own from sheet material?
You can, but matching the thickness and the material grade matters more than matching the outline, and on joints that set a clearance it is not worth the risk.
Q: Does it need sealant as well?
Normally no. A clean face and even torque is what makes the joint, and sealant mostly makes the next disassembly harder.
Q: Why does the joint weep after retorquing?
Once a gasket has taken its set, retorquing rarely recovers it. The fix is a new gasket on clean faces.
Q: How should spares be stored?
Flat, dry and away from heat. A gasket that has creased or curled in storage will not seat evenly.
