Uponor QS fittings

Steve Minnich

I no longer own the ProPex expanding tools so when I connect my home runs to the manifold, I’m going to use the Uponor QS fittings as I’m using Uponor hePex and their SS manifold. I used them a long time ago without issue, but for years now, I used Nylog White on almost anything that’s threaded. It’s like Frank’s Red Hot Sauce, I put that sh@t on everything. Any chance that it might cause over tightening because it’s a lubricant, or any chance it could somehow damage the O-ring?

I've never used it but based on the nylog white data sheet I would think its just fine.

Thank you! I shall proceed apace.

really no need to use any on tread sealant that connection, the sealing is at the o ring connection into the manifold port

The nut and compression ring just locks all together

I would still use some lube on the O-Ring.

Food grade grease

I used the white Nylog. Old habits die hard.
