Viega 77457 – Frequently Asked Questions
1) Is the Viega 77457 tee all press connections, or does one outlet thread?
All three outlets on the Viega 77457 ProPress tee are press connections, listed as P1 x P2 x P3. Nothing on this fitting threads or solders, so you need a press tool with the correct 1-1/2 inch jaw or ring and actuator to make up any of the three ends.
2) Will the Viega 77457 press onto 1-1/2 inch type L copper tube?
Yes. The 77457 is a copper ProPress tee sized 1-1/2 x 1-1/2 x 1-1/2 inches, so it presses onto nominal 1-1/2 inch rigid copper tube on all three ports. It is a copper-body fitting, not bronze, so keep it on copper tube runs.
3) Can I use a Viega ProPress copper tee to replace a soldered 1-1/2 inch copper tee in an occupied building?
That is the usual reason to reach for it. The 77457 presses onto the same 1-1/2 inch copper tube a sweat tee solders to, so you cut the old tee out, clean and deburr the tube ends, mark insertion depth and press. No torch, no hot work permit, no draining the system dry for flame clearance.
4) What does Smart Connect do on a Viega ProPress tee, and do I still have to press every joint?
Smart Connect is a feature of the sealing element that lets an unpressed connection leak a small amount during pressure testing, so an un-crimped joint shows itself before the wall closes up. It is a verification aid, not a substitute for pressing: every one of the three ports on the 77457 still has to be pressed to be a finished joint.
5) When should I order the exact Viega part number 77457 rather than a generic press tee?
Spec sheets and submittals call the fitting by manufacturer part number, so order it as Viega 77457 when a drawing or a standardization list names ProPress. It is made in Germany and carries UPC 691514774572 if your purchasing system matches on that. Press systems are not interchangeable between brands at the sealing element, so keep one system through the run.
