## Overview

This 3-pack of 3.5-inch diameter O-rings is designed for APEC ROES-50 and other 10" standard reverse osmosis filter housings. Lightweight and NSF-compliant, these durable O-rings ensure a secure, leak-free seal and are recommended for replacement every 1-2 years to maintain optimal system performance.

## Description

These durable O-Rings are compatible with APEC Essence and Ultimate reverse osmosis systems and can be used on other 10" standard sized filter housings as well. They are light weight and asy to install, working great with Dow Cornering 111 Compound lubricant or any other brand food type lubricant for maximum leak seal. Recommend to replace O-Rings every 1-2 years.

Review: They work fine but these should really be included with the filter cartridge since they recommend replacement with every filter change. I rank these high though because after a year on the system, they still looked like they were brand new and could be used again. I still changed them just because they are cheaper than a flooded house and not worth the risk.
