quad ring for regulator stem replacement?

my quad ring (o-ring) that is on the step of the regulator is pretty torn up. I was looking to replace it but am having a hard time finding one. Does anyone know where to get one? I have tried measuring it which comes out to be close to
OD - 5/8"
ID - 3/8"
Width - 1/10"

Mcmaster sells one close but with a 1/8" width and im affriad it might be too big. Has anyone found a good cheap replacement for this ring? I ordered some rubber washers from kegconnection but i dont know if this will work

what is a quad ring? A 4 ring oring? Never seen one Got a picture.

the quad ring looks like a X instead of and O I would post a pic but it never works for me i am doing something wrong

Are you talking about the gasket between the tank and the regulator high pressure nut?

I just went to the hardware store - In the nylon washer drawer. Find one that fits the nut, with the smallest diameter inner hole.

Then tighten the bejesus out of it.

2 tanks through mine without a leak, and it cost $.35 :rockin:

Yeah the washer on my reg was nylon aswell.......... until I lost it

or buy a brass one and never replace it for 5 lifetimes as brass on brass (both machined) are self-sealing.

i was able to get a 1/8' diameter o-ring at ace hardware for 29 cents that worked well. I also ordered some rubber washers with an order for some other stuff that i might try as well. Taprite who makes the regulator said the quad ring was suppose to seal better but that a normal o-ring works fine.

I lost my gasket and cut a rough circle out of the bottom of One of these and poked a hole in the middle. Has lasted 2 tanks without leaking

Kind of like these only bigger? http://www.mcmaster.com/#90025k368/ (those are the ones I use on corny dip tubes.

Once there, click on the Replacement Parts tab. Look for #14 in the list.

Quad rings are made to fit in the same grooves as O rings. The quad ring may work better, but O ring works fine. Use the same O ring that fits on ball lock post. The trick is to remove the center spud of the regulator inlet using an Allen wrench. It has a taper on it to hold the ring in place but that makes it almost impossible to install the ring unless you remove it first
