Viega 78052 – Frequently Asked Questions
1) What size copper tubing does the Viega ProPress 78052 coupling fit?
The Viega 78052 is a 3/4 inch by 3/4 inch ProPress coupling, so it joins two runs of 3/4 inch copper tube. Both ends are press ends (P1 x P2), meaning nothing is soldered or threaded, both sides get crimped with a press tool.
2) What does "with stop" mean on a ProPress coupling, and when would I want one without?
A coupling with a stop has an internal ridge in the middle, so each tube end butts against it and seats at a fixed insertion depth. That is what you want on a normal joint between two cut lengths, because it sets your depth for you. A coupling without a stop (slip type) lets the tube pass through, which is what you use for a repair where you cannot pull the pipe apart to slide a fitting on. The 78052 is the stop version, in 3/4 inch copper.
3) What is Smart Connect on the Viega 78052 and why does it matter on a big job?
Smart Connect is Viega's unpressed-joint feature: an unpressed fitting will leak visibly during pressure test so you find the one you missed instead of finding it after the walls are closed. On a run with dozens of 3/4 inch couplings, that is the difference between a quick test and chasing a drip. The 78052 carries it.
4) Is the Viega 78052 coupling copper or bronze, and can I use it on my copper water lines?
It is a copper fitting, made for copper tube systems. Material matching matters here: putting a copper press fitting into a copper potable or hydronic run keeps the joint from being a dissimilar-metal point. For steel or stainless systems you need the matching ProPress line in that material, not this one.
5) How much room do I need around a 3/4 inch ProPress coupling to get the press jaw on it?
The fitting itself measures 1.248 x 1.248 x 2.008 inches, so the body is short but you have to allow clearance for the jaw around the full circumference of each press end. Tight joist bays and back-to-back fittings are where crews get caught out, so plan the fitting spacing before you cut.
6) Do I need anything besides the Viega 78052 coupling to make the joint?
The coupling ships with its sealing element already installed, but the joint needs a press tool with the correct 3/4 inch jaw or ring. No solder, flux, torch, or fire watch. You still have to deburr and clean the tube ends and mark your insertion depth before pressing.
7) Is the Viega 78052 made in the USA? I have a domestic-content requirement on this job.
Yes, the 78052 ProPress coupling is made in the USA, which is what institutional and government buyers with domestic sourcing language in the spec need to see on the submittal.
8) What part number do I order for the Viega 3/4 inch ProPress copper coupling with stop?
Order Viega part number 78052. That is the 3/4 inch x 3/4 inch copper ProPress coupling with stop. The number is the whole spec, there is no finish or handing choice to make with it.
