### ⭐⭐⭐⭐⭐ Good replacement for original
*by B***F on 9 August 2019*

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.

### ⭐⭐⭐⭐⭐ Worked for me
*by T***H on 4 January 2020*

Worked well - saved our softener from the trash heap.

### ⭐⭐⭐⭐⭐ Easy to replace
*by A***R on 6 October 2020*

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.
