why is it called an adapter? i have 2 inch U11-200P STA-RITE P.V.C. union, I need O-rings can you help thanks Dave

A  Answered on 5/27/2017 by InyoPools Product Specialist Patrick P.

Hi Dave, sometimes an o-ring can fit several items, this is my guess on why the product name says adapter o-ring. However, the 5057-26 is the correct o-ring for the Sta-Rite U11-200P union. You can view your Union parts on the Sta-Rite Union Page I believe your union is the second picture.

Hi, Robert. Yes, this is the correct o-ring for the Max-E-Pro Union.

Unscrewed big union nut, removed old o-ring with a pick tool. Put new o-ring in groove and tightened union nut to hand tight.
