Water Softener O-Ring Seal Kit, 4-Pack (Part: 7337571, 7170288, STD302213, WS03X10025)

These O-rings are very slightly smaller than the originals but they work fine as a replacement. I have had no issues with them and they are working as they should.

Fit just like they should and very easy to replace. Unfortunately I discovered I needed the bypass valve itself and had to go back online and buy that. apparently the plastic edges of the bypass valve were chipped and that's why it was leaking so I recommend you just go ahead and buy the bypass valve assembly.

Item was delivered when expected. They worked perfectly for what we needed them for.

I didn't know that the clip that holds the pipe in place gets brittle in just a few years, so the clip broke. The O-ring fits, but I had to improvise to make due until I can get the clip.

2nd time I've ordered from them. Both times a piece of cake. No problem with the O-rings. Easy transaction.

Excellent price for a non-standard part. The O-rings at Lowes and Home Depot were all a little too big, too small, or too narrow. Much cheaper and faster than paying the $100/visit for a water softener repairman to give me two O-rings.

It is good to have the exact part and one day shipment, but found out later that ACE Hardware had the same o-ring for $0.79 each. (my leak problem was not the o-rings, but the by-pass valve intake to the softener connection. Replacing the by-pass valve fixed the leak. )

The rings fit perfectly and the problem was resolved.
