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 do. Petroleum and Butyl rubber are completely compatible.
Use of Vaseline on Buna-n O-rings is a standard procedure.

the manual for my pool pump said to use silicone grease. i know rtfm is

Most O-rings are Buna-n, some are Viton, others are Teflon.
Vaseline is compatable with all of them.

The small amounts of Vaseline that may enter the water will cause no
harm. Vaseline is non toxic.

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
to paint?

Petroleum Jelly (Vaseline). As tnom has stated it is eatable and worked
for me and a host of mechanics for over forty years. Even used it on poly
packing. Easy to see if contaminated and what the contaminate is. A metal
shaving or grit in a dark grease will lead to rework. The most expensive
work because it it at no profit and may ruin your reputation. Your
reputation is hardest part of rework to repair.

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
>you paint the inside of your pumps?
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
jobs.

I recommend plumbers grease, it is much tackier then most lubes & lasts
much longer before washing/wiping away.

What if the OP's pump body is plastic? The lube has to be compatible
with all the material it contacts....
tn...@mucks.net
The question was about O-rings. Not plastic.
Most plastics fair well will petroleum.

I didn't say it was harmful, I said it wasn't approved for potable water
systems...
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...

Back in the day when I was learning how to rebuild scuba regulators and valves I
was warned NEVER to use petroleum jelly or oil on a rubber o-ring as the
petroleum products would eventually attack and destroy rubber. We used silicon
grease.
A little goes a long ways. We would apply enough to make the ring appear
wet.... but not enough to leave any excess glop on the ring.
Food grade silicon grease was available from restaurant supply houses. Dive
shops sometimes had it as well. And silicon spray is NOT the same as the
grease; it won't last nearly as long.

They were wrong as far as O-ring compatibility. Perhaps the valve or
other material is what is in question, not the O-ring.

EPDM rubber is not compatible with Vaseline. Is this what scuba gear
uses? It may be because respirators use it. This is the same type of
rubber that automotive door seals are made of.
EPDM is not used as O-ring material in pumps.

Correction: Change -Butyl- to Buna-n
The Daring Dufas
would learn the difference.

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

In the context of a lubricants that may be ingested Vaseline is pure
and Silicone lubricant is not. Silicone lubricant has unknown added
ingredients that would make me hesitate.
