Viega 77417 – Frequently Asked Questions
1) What pipe sizes does the Viega 77417 ProPress tee connect?
The Viega 77417 is a reducing press tee sized 1 inch x 3/4 inch x 1/2 inch, so the run goes 1 inch to 3/4 inch with a 1/2 inch branch takeoff. It is a copper fitting with press ends on all three ports, so it mates with standard copper tube of those nominal sizes. Because the three ports are all different sizes, orientation matters when you dry-fit the assembly.
2) Do I need solder or a torch to install the Viega 77417 tee?
No flame, no solder, no flux. The 77417 is a ProPress copper tee that is joined with a press tool and the correct jaw or ring for each port size, so you need jaws for 1 inch, 3/4 inch and 1/2 inch to complete all three connections. That makes it workable in occupied buildings and finished spaces where a hot work permit would otherwise be required.
3) Can I use the 77417 tee if my branch line is 3/4 inch instead of 1/2 inch?
No. The branch on the 77417 is fixed at 1/2 inch press. For a 3/4 inch branch off a 1 inch run you need a different Viega ProPress reducing tee part number sized for that combination. Reducing at the fitting is cleaner than pressing a full-size tee and adding a reducer, so match the part number to the three sizes you actually have.
4) What does Smart Connect technology do on this Viega tee?
Smart Connect is Viega's unpressed-connection feature: an unpressed fitting will leak visibly during pressure testing so the installer can find it before the wall closes up. On the 77417 that applies to each of the three press ports, which is worth knowing on a reducing tee where it is easy to press two ends and miss the third.
5) How much room do I need to fit the Viega 77417 tee between other fittings?
The 77417 measures 3.386 inches across, 2.28 inches high and 1.5 inches deep, and it weighs 0.358 lbs. Lay that out against your stub lengths before you cut, since a press tool jaw also needs clearance around each port to close fully.
6) Is the Viega 77417 copper or bronze, and does that matter for my system?
It is a copper-body fitting, which is the standard choice for copper tube domestic water and hydronic runs. Keep it with copper tube rather than mixing it into a steel or PEX run, where you would need a transition fitting instead.
7) What is the manufacturer part number for the 1 x 3/4 x 1/2 Viega ProPress copper tee?
Order Viega part number 77417. That number covers the copper ProPress tee in the 1 inch x 3/4 inch x 1/2 inch reducing configuration, and the fitting is made in Germany. Distributors cross-referencing a customer's list should note the size order, since Viega uses separate part numbers for each combination of run and branch sizes.
