I am thrilled to share my positive experience with the o-ring replacement for my water softener bypass valve seal. The product exceeded my expectations in every way, earning a well-deserved 5/5 rating.First and foremost, the o-ring replacement was incredibly easy to install, thanks to clear and concise instructions provided with the product. Within minutes, I had successfully replaced the old seal with the new o-ring, and the results were immediate.Not only did the replacement effectively seal the bypass valve, but it also resolved the leak issue I had been experiencing with my water softener. The quality of the o-ring is top-notch, as I haven't encountered any issues since installation.Furthermore, the affordability of this replacement o-ring makes it an absolute steal. I appreciate the cost-effective solution this product provided, saving me both time and money in the process.Overall, I am extremely satisfied with the performance and value of the o-ring replacement for my water softener bypass valve seal. I highly recommend this product to anyone in need of a reliable and durable seal replacement. It has truly made a positive difference in the functionality of my water softener system.

After servicing my soft water tank, with a Fleck 5600, I had a small leak at the bypass valve assembly. While this set of 4 o-rings were a bit pricey, they came in two days, fit perfectly, and fixed the leak.

Don't know what to tell you at this time....They fit because I got the right size,but, be careful that you do not get the wrong one...These went onto my WaterSoftener and all is well at this time....Will keep you posted, if you wish.

The o rings fit perfect on my Fleck 5600 sxt water softener. Make sure you coat the ring with vegetable cooking oil before installing. Do not waste your money on plumbers silicone.

The product itself is great and worked properly. But almost $15 dollars for four 1" orings is pretty ridiculous. I only paid this because I knew they would be the correct size. No one publishes the oring dimensions as to keep them proprietary to the manufacturer and supplier. I will remember this.
