Viega 77452 – Frequently Asked Questions
1) What pipe sizes does the Viega 77452 ProPress tee connect?
The Viega 77452 is a reducing press tee sized 1-1/4 inch x 1-1/4 inch x 3/4 inch. The run is 1-1/4 inch on both ends and the branch outlet drops to 3/4 inch, so it's the fitting for taking a 3/4 inch branch off a 1-1/4 inch copper main. All three ends are press connections (P1 x P2 x P3), not sweat or threaded.
2) Can I use the Viega 77452 to branch 3/4 inch off an existing soldered copper main?
Yes, as long as the main is 1-1/4 inch nominal copper tube. Press fittings go onto the same copper tube as sweat fittings, so you can cut in the 77452 between two soldered sections. What matters is the tube surface: the press area has to be clean, round, undamaged and free of old solder or deep scoring, because the seal rides on the outside of the tube.
3) Is the Viega 77452 tee copper or bronze?
Copper. The 77452 ProPress tee is a copper-bodied fitting, so it is intended for copper tube systems and keeps the joint metallurgically consistent with the pipe. Bronze and stainless press fittings exist in the ProPress line for other applications; this one is the copper version.
4) What does Smart Connect technology actually do on this Viega tee?
Smart Connect is a feature of the sealing element that lets an unpressed joint leak intentionally during pressure testing. On the 77452 tee, that means if one of the three sockets gets missed, the test shows it as a small weep instead of hiding until the system is in service and buried behind finish. It is a verification aid, not a substitute for pressing every socket.
5) What is the manufacturer part number for the Viega 1-1/4 x 1-1/4 x 3/4 ProPress copper tee, and where is it made?
Order it as Viega part 77452. It is manufactured in Germany. That is the number to quote for a reducing copper press tee with 1-1/4 inch run and 3/4 inch branch, which keeps it from being confused with the full-size 1-1/4 inch x 1-1/4 inch x 1-1/4 inch tee.
6) Is this tee the right choice for potable water, or should I use something else?
The 77452 is a copper potable-water-style press tee for plumbing systems. For a hydronic or mechanical branch at the same sizes you would typically look at the bronze or stainless ProPress equivalents depending on the medium; for anything other than copper tube, a press copper fitting is the wrong family entirely.
