Alpha1 Posted April 21, 2021 Report Share Posted April 21, 2021 Is there any location in Chapala or Ajijic that sell o-ring lube? I haven't had any luck so far. Even tried Autozone. Quote Link to comment Share on other sites More sharing options...

happyjillin Posted April 22, 2021 Report Share Posted April 22, 2021 You don't need anything special. I just use grease like the last time I put a new o-ring in my Amal carb. Quote Link to comment Share on other sites More sharing options...
barrbower Posted April 22, 2021 Report Share Posted April 22, 2021 I use dielectric silicone grease which is available at Autozone. I use it for the o rings and threads on my water filters as well as a variety of automotive applications. Alan 2 Quote Link to comment Share on other sites More sharing options...
Mainecoons Posted April 22, 2021 Report Share Posted April 22, 2021 Vaseline works well also but Alan's recommendation is the best. Quote Link to comment Share on other sites More sharing options...
lcscats Posted April 22, 2021 Report Share Posted April 22, 2021 Vaseline for water filters not sure Dielectric grease for cars is edible but probably wouldn't hurt you but I will pass. Quote Link to comment Share on other sites More sharing options...
TelsZ4 Posted April 22, 2021 Report Share Posted April 22, 2021 If the o ring didn’t come with a little packet of lube. I’ve always used Vaseline. Quote Link to comment Share on other sites More sharing options...
barrbower Posted April 22, 2021 Report Share Posted April 22, 2021 Some petroleum products will degrade some rubber products so be careful. The dielectric silicone is not water soluble and the surfaces where it is applied on the threads are not exposed to water. The o ring is quite compressed and very little surface is exposed to the water. After a year of use the o ring still has the same light feel of silicone grease as when I applied it. You probably have move degraded polyvinyl chloride getting into your water than grease. I think in the USA PVC is no longer legal for use in drinking water supplies for that reason. Only used for drain, vent, waste, and irrigation. They now use CPVC, PEX, or copper but PVC still used widely in Mexico. Alan 1 Quote Link to comment Share on other sites More sharing options...
barrbower Posted April 22, 2021 Report Share Posted April 22, 2021 By the way, I'm also pretty sure that the little package of lube that sometimes comes with o rings is also silicone grease...even for drinking water applications.

happyjillin Posted April 22, 2021 Report Share Posted April 22, 2021 The o-ring is a rubber gasket/seal which only needs grease,vaseline,etc. to hold it in place before using the proper ft/lbs applied to the 2 parts fasteners. Once the o-ring is in place and the 2 parts are tightened, hardly any of it is exposed to whatever flows through the 2 joined pieces.

I don't want them to get stuck. Also they suggest using Teflon. I will pass on that. Note this is about pool filters not drinking water filters.

You only need to worry about the pipes from the block carbon/charcoal filter to your tap as it will remove most of the PVC chemicals. Ignore this if you have a reverse osmosis filter at your kitchen tap as that will take care of the PVC chemicals even better than charcoal/carbon filters.

AndyPanda Posted April 23, 2021 Report Share Posted April 23, 2021 Are we asking for the right thing? Any auto store without lube or mechanic's grease ain't right. Quote Link to comment Share on other sites More sharing options...

They all have it. And an o-ring only requires something to hold it in place until proper tightening of the 2 pieces it's between and yes I speak from many years of experience. pedro kertesz Quote Link to comment Share on other sites More sharing options...
Mostlylost Posted April 23, 2021 Report Share Posted April 23, 2021 I have never put lube on any o ring and have never had a problem. 1 Quote Link to comment Share on other sites More sharing options...
