Re: [PSUBS-MAILIST] gluing O-ring into grove?

["Mark Steed" <plutomark@mail.astate.edu>]

William: I have had similar experience. What worked for me was really putting the heavy clear silcone grease( not glue!) all over the offending ring and groove. This worked on a nylon flange very similar to a swimming pool filter cover. Also about the same 2 foot diameter. Pressure was in the 50psi range. Seemed that "dry" spots on the o-ring allowed for it to pop out. Good luck and best regards- Mark
