Terrific product easy to install and solved my problem- wish I had purchased the complete kit vs this as after disassembling I saw the bottom seal needed replacing too. I recommend this brand!

O-Ring between Bonnet (black cap) and body wrong size (too big). Reused original O-Ring and installation was a breeze. Would have been nice to have a one page illustration/component stack-up illustration provided; was able to find one on-line. Else wise, provided components worked well.

Everything fit perfectly except the o-ring was too small. It’s listed as 2.125 which it should be. The supplied o-ring was about 3/32 smaller. Thank goodness I had one the right size.

This is a great kit. This saved me a bunch of money and time rather than replacing the whole assembly. The install wasn't difficult. Although the instructions weren't exactly step-by-step. For the price alone, I'd recommend this kit.
