Depends entirely on what the o-ring is made from.
But, probably not a good choice for potable water, certainly not if in
contact (altho a minimal risk, isn't approved for food contact).
I'd ask OP _what_ o-rings, what kind/style of pump, etc., ...
Depending, may not need any lubrication and/or may be detrimental to
performance/longevity or may be water-lubricated or...
I didn't say it was harmful, I said it wasn't approved for potable water
I was lit up a few months ago by somebody else on the other way 'round
when I suggested it for the water filter o-rings. So, thinking same
way you did/do, I looked it up and it is _not_ listed for internal use.
That said, I personally still use it but no longer recommend it in
usenet postings for the purpose...
You can use silicone grease but it is more costly and really isn't
needed. What would you rather ingest? Vaseline or Silicone?
Have you ever tried to get rid of a Silicone residual when trying
neither, but silicone is inert and vaseline is oil based. you can buy a tube
of it in an auto parts store for about the same price as a tub of vaseline.
look for boat trailer bearing grease.
i have also read that some o-rings will disintegrate if used with oil based
lubricants; manuals explicitly state not to use it on some pumps that i
have. i can't tell the difference between materials of o-rings and would
rather not risk it.
you paint the inside of your pumps?
Please Quote. Vaseline is 100% compatible with O-rings.
They are speaking of mechanical seals. Do not use petroleum on
mechanical seals. Use glycerin
No, but Silicone residue is mostly invisible and hard to get rid of.
If silicone use becomes standard procedure for lubrication around
the house then expect the residue to end up on painted surfaces.
If it ends up on painted surfaces you should expect problematic paint
Silicone, of course, It is inert and will pass through the digestive system.
That is one reason silicone is used for medical devices with body contact.
Petroleum jelly is used on cosmetics and on cuts because it is safe too.
Lots of uses for it.
Not to mention as a cheap sex lubricant
