Viega 77057 – Frequently Asked Questions
1) Will the Viega 77057 press elbow work on 1 inch copper water lines?
Yes. The 77057 is a 1 inch x 1 inch copper press fitting, so the press end goes over nominal 1 inch copper tube and the FTG end drops into a 1 inch copper socket. It's copper bodied, matching the tube it joins.
2) Do I need a regular 90 or a street 90 for my copper press job?
Use a street 90 like the Viega 77057 when the turn lands directly on another fitting: its FTG end plugs into a fitting socket, so you only press one joint instead of cutting a stub of tube and pressing two. A standard press 90 has press sockets on both ends and is what you want when the elbow sits between two runs of tube.
3) How much room does the Viega 77057 1 inch street elbow take up in a tight wall cavity?
It's a compact turn: 3.02 inches in height and width, 1.5 inches in length, and it weighs 0.265 lbs. Remember to leave clearance around the press socket for the jaw of your press tool, not just for the fitting body.
4) What is Smart Connect on the Viega 77057 and why does it matter on a big job?
Smart Connect is the unpressed-joint detection feature built into the ProPress fitting. On pressure test, a connection that was missed leaks visibly instead of holding, so you find the skipped press before the walls close up. On a run with dozens of joints that's the difference between a quick test and hunting a callback.
5) Can I solder the Viega 77057 instead of pressing it?
No. It's a press fitting with a sealing element in the socket, and it needs a press tool with the correct 1 inch ProPress jaw to make the joint. Heat would ruin the seal. If the job is being sweated, use a standard solder street 90 instead.
6) Is the Viega 77057 copper or is it a bronze press fitting?
Copper. The 77057 body is copper, so it's a like-metal joint on copper tube with no dissimilar metal concern at the connection. It's made in Germany.
