My 10 year old regulator had its check valve fall out and I can’t get it to screw back in. Is there a way to fix it or remove it and replace? It looks like I should be able to unscrew it and replace the whole part but, for the life of me, I couldn’t get the valve to budge. So solid I’d swear it was welded.
It’s highly unlikely that it’s welded, but they will use a lot of torque when tightening those things (and more than likely use something like loctite). When I replaced some hose barb fittings with MFL fittings on one of my manifolds, I wound up having to use a C-clamp on a work bench to get the leverage needed to hold the body in place.
It’s not welded. We’ve been selling taprite products for years. Above answers are correct. It is 1/4" NPT. They have been using a thread lock product along with the teflon tape, maybe that’s your issue.
The part number for a replacement from Taprite is 1600C. Grab one from us or support a local business and pick one up there! Most shops will replace it for you with their equipment. I know we do, but unless you’re in Seattle you might be out of luck…
