Have you compared PVC union o-ring material?

[Saltyreef]

Im sure many of you have come across this topic, maybe theres posts out there already.....

Just wondering if anyone has noticed and compared the different oring and seal materials on pvc unions and or valves.

The off the shelf spears unions at my local plumbing supply came with EPDM (black and more cost effective) and cost $15 & $20 for 1/2" & 1"

The BRS spears unions are 3.99 & 4.99 for 1/2" & 1" and......drum roll.......Viton O-rings.

THANK YOU BRS!

Those spears unions are nice, though they’ve put the O ring on the flange side which totally screwed me up. Not sure the O ring material really matters all that much. I’ve a few ball valves on my system with EPDM that are over 20 years old ..... still seal just fine.

I agree it doesnt. Not unless youre using it for chemicals. We do at work so Viton is the go-to O-ring material.
I wish more of the engineers knew the difference of seal materials and the chemicals I use to treat the steam system we all work on.
Cant tell you how much rubber comes out of the test port on our condensate return line from failed seals in the valves theyve used on repairs in the past.
This means hardly nothing to a reefer but just know BRS is giving the BEST quality at the LOWEST price.

That makes sense.

That makes sense.

The only reason i know this is because im impatient and paid for fast shipping then went to the plumbing supply store the same day lol.

$25 order vs $80....

Is it bad that I completely understand ...... as much as enjoy the biology of reef tanks, part of me is a complete gear geek.
