## 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: Not leaking and held up well over time - 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.
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

### ⭐⭐⭐⭐⭐ Not leaking and held up well over time
*by A***R on February 8, 2025*

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.

### ⭐⭐⭐⭐⭐ Good fit
*by S***S on September 12, 2024*

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

### ⭐⭐⭐⭐⭐ Worked perfectly the first time. Be sure to order the correct version.
*by A***R on March 28, 2019*

I had no trouble replacing the o-rings for the three primary filters on my APEC Reverse Osmosis system and these o-rings worked perfectly in every respect. I did read some reviews indicating the o-rings were thinner than the originals, had a larger outside diameter than the originals and/or did not seal properly. I saw none of those problems and think I may know how to avoid those issues: • First and foremost, be sure to order the correct version. There is a Type “A” for systems manufactured before a certain pair of dates and a Type “B” for systems manufactured after those dates. Clicking on the Type “B” box will provide those dates. Be sure to select the correct (“A” or “B”) box before proceeding with ordering. My system was manufactured in 2018 so I ordered Type “B” and the replacement o-rings appeared identical to the originals. • I used food grade o-ring grease on all 3 o-rings and on the flat rubber washers at each end of the two carbon filters which I was installing. I spread the grease thinly but thoroughly over the surface of all items. The grease prevents friction loads which can damage rubber parts and can give a false indication of the torque applied. There are many brands available; I used Haynes Lubri-Film sanitary lubricant which costs about $8 for a 4 oz tube but will lubricate many o-rings per tube. • I used the wrench provided with the original set to tighten each filter case after installing. I pulled until each was a little more than firm; perhaps a 5-8 lb pull on the wrench. Good luck. I hope this has been helpful.
