## Customer Reviews

### ⭐⭐⭐⭐⭐ good price and works good.
*by G***D on April 11, 2025*

It will last a year an is worth the money to know it will not leak.

### ⭐⭐⭐⭐⭐ Great replacement
*by A***O on September 9, 2024*

These O-rings are a great fit and replacement part for the Fluval 307 and 407 cannister filters. Whenever I do filter maintenance every 3 months I change out the O-rings. Filter has never leaked or given me issues on fitment.

### ⭐⭐⭐⭐⭐ Works great
*by C***K on February 8, 2025*

Original Fluval O-ring broke in 2014 and leaked all over the floor. It created a syphon and dumped approximately 30 gallons of water from my turtle's tank onto the floor. Since then, I periodically change the o-ring with these (about once every 2 years) and have not had a problem. Works as advertised.
