Where to get Cepex O rings.

[USMA36]

I have a 1.5 inch Cepex ball valve that has a very slight leak. I’ve tightened it as much as I dare and I have also used some silicon lubricant on the rings, but it’s still dripping from the union. Where in the world can I buy replacements? BRS only has up to 1.25 inch replacements.

I would check plumbing supply stores, or Grainger. Most hardware store won't have anything that big.

ACE and DIY have the O-Rings. They keep them in the little shelf units in the Plumbing section
