    "O" Ring grease, lube?

    So far I have not used any lube/grease on the Filter/Pump basket "O" Rings and I was wondering what kind to use next time I clean my Cart Filter. Is lithium grease ok to use or is it Teflon?

    Thanks,

    You just need a waterproof o-ring lubricant. It doesn't matter whether it's silicone or teflon based.

    Most pool supply stores sell silicone and/or teflon grease. I have always used the silicone kind but either one is ok.

    information in my sta-rite manual says not to use silicon of any kind on an o-ring as it will apparently eat the ring over time. echoed by the pool store i deal with locally who have yet to lead me astray. if necessary at all, a graphite spray is recommended instead for o-rings. very slick.

    That's odd. This Sta-Rite owners manual (http://www.staritepool.com/pdf/S454(7-24-03).PDF]) calls specifically for silicone lubricant in the event the original o-ring is replaced. To wit: "If you replace the O-Ring with a non-internally lubricated O-Ring, you may need to apply a silicone based lubricant" (page nine of the .pdf).

    Hey all, as long as it's not petroleum based, it should be cool to use on your o-rings. 8)
    As a side note, I've found the silicon based lube softens my fingernails , I asked (and for a change, the request was honored ), to get only teflon based lube since I use a few oz of it per day at this time of year

    Lowe's sells a product called "plumber's grease" which is great for pool o-ring use. It's non-petroleum based and gives a great water seal.

    i saw the plumber's grease when i was rebuilding my pump and wondered if it could be used for that application and it's easy to find!

    If the grease is NOT petroleum based it will not attack o-rings. The lubricants sold for pool use are not, whether silicone or teflon based.
