Reactor Oring

roc5288 · May 28, 2019

Hi guys. Long story short I purchased a old reactor from a forum member but did receive the O ring with it. It’s a nextreef MR 1. Having a hard time locating one being they have been out of business for sometime now.
If anybody can point in the right direction I’ll appreciate it.

You probably already know this, but in case you don't all you really need is the spec for the O ring. You need material (probably just black rubber), material diameter, and o ring diameter. Then you can buy from anywhere. Most industrial suppliers sell o rings and there are kits to make your own.

Yeah. I’ve been to like HD, Lowe’s. That proved to be useless.

If you know what you are after try Mcmaster Carr or something similar.

I know it’s 4.5”. Not sure on thickness.

That's tough. Best bet is to find someplace with a store front and test fit a bunch or find someone who can measure one for you.

Lowe's/HD are pretty useless once you get out of the common stuff.

4.5" is about 118mm. Here is a link to an oring that might fit, but you'll want to confirm your measurements as well as ensure that it is made of the proper materials for the application. Salt water isn't nice to quite a few materials.
