I'm trying to source my pool equipment o-rings by trade sizes and material.
I've figured out all the trade sizes; but does anyone know the material?

Buna? Viton? Nitrile? Silicone? Butyl?
Does it matter?

If nobody knows, I'm going to go with Viton; but it would be better to
know for sure what the OEM material is for pool pump o-rings.

I doubt it really makes much difference. Swimming pool water is about
as benign a fluid as you can find.
When I lived in DC my city water tested "ideal" on a 2 bottle pool
tester.

If you are actually in the chlorinator itself, that is a more hostile
environment.

DDD-
If you want to educate yourself to reasonable level about O-rings &
O-
ring material apps,' go to McMaster Carr catalog and search on O-
rings.

If you REALLY want to learn about O-rings

Hint.... my dad & I used o-rings in pools for many years without ever
researching materials.
Pool O-rings ain't rocket science or PhD work.

"I was thinking sunlight + water + chlorine + acid was the
environment.
Pool water is nearly drinkable except for the salts / hardness level.

Calm down....you're over thinking (& incorrectly at that) nearly
everything you approach.

Ya know...your calls to all the mfr's may seem "free" but the true
cost is coming out of the shareholders or owner's pocket.
Reduce the clutter......

Get some Buna-N's from McMaster & be done.
If they fail (which they won't) replacement with EDPM.
