## Overview

This 3-pack of replacement O-rings is engineered for APEC ROES-50 and other 10" standard reverse osmosis filter housings. Made from NSF-compliant materials, these lightweight O-rings ensure a durable, leak-proof seal that’s easy to install and built to last 1-2 years, protecting your water system from costly leaks and maintaining optimal filtration 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: Perfect replacement for my 3 stage filter manifold - I have a Reverse Osmosis 5 stage filter system and the 3 main stages are canister filters. Every year I replace the O-rings as we have hard water that mineralizes everything it touches. I use food grade silicone to condition the O-rings and make sure both the manifold and canister holders are clean and dry before installing. Every year I get a fair amount of black residue to clean off but these haven't leaked due to O-ring failure in 10 years. I did have to replace the manifold once due to cracks that caused leaks but the O-rings never failed. As these are APEC I know they are designed to fit with both circumference and thickness of the O-ring. Some parts you don't want to rely on aftermarket fitment as they may not be the correct size or use the correct material and can lead to failure and leaks.
Review: Good fit - These fit, as they should once, I figured out how to remove the old ones. It was easy to replace them. They are a good value for the money. The thickness matches, where it needs to to keep everything sealed. They seem to be of higher quality and they appear to be very durable
