So going some years back when we had a pool, the filter was a sta-rite stainless number with a cartridge in it. The housing split in the middle and had a clamp that held the 2 halves together and a large o-ring did the sealing. Second time I was having to replace the o-ring the pool parts store guy asks if I use "o-ring seal". That seal lasted 8 yrs, maybe even more as we moved -- the grease was the trick...
that stuff was just pure silcone grease, which most folks (other than us) use for things like spark plug boots (also known as di-electric grease).
I use the stuff on all o-rings and in particular ones having to do with water (like all the ones on my well filter system) -- no leaks and never stuck.
Has anyone tried this stuff on a coolant filter? I'm happy to be the first if not... filter system goes on next week (finally).
THANK YOU! I struggle each fall to winterize my barn (to prevent freeze damage) in Colorado 'cause removing the water filters on the treatment system is a PITA. I will try silicone grease on the O-rings next spring.
Here is a thread showing how I relocated the filter to make it easier to get out of there. Helps get the wrench on, and helps limit how much coolant spills all over.
