Viega 15518 – Frequently Asked Questions
1) What pipe sizes does the Viega 15518 ProPress tee connect?
The Viega 15518 is a reducing press tee sized 2 inch run by 1-1/4 inch by 1-1/4 inch. All three ends are press connections (P1 x P2 x P3), so it takes a 2 inch copper main with two 1-1/4 inch copper branches. It is not a threaded or sweat fitting on any port.
2) Can I use the Viega 15518 press tee on copper tube, or is it for PEX?
Copper only. The 15518 is a copper-bodied ProPress fitting made to press onto copper tube at all three ports. Viega's PEX systems use a different fitting line entirely, so don't mix them on the same connection.
3) What does Smart Connect mean on a Viega ProPress tee?
Smart Connect is the feature built into the sealing element of the 15518 tee that lets an unpressed joint leak on purpose during pressure testing. That way an installer finds the connection that was missed before the wall closes up, rather than after.
4) How much room do I need to fit a 2 x 1-1/4 x 1-1/4 ProPress tee between other fittings?
Plan the rough-in around 5.394 inches across, 3.646 inches in the other direction, and 2.594 inches on the remaining axis. You also need clearance for the press tool jaw or ring to seat square on each port, which is more than the fitting body alone occupies, so keep it off tight against joists or studs.
5) Do I need a special tool for the Viega 15518, or can I solder it?
This is a press fitting, not a solderable one. A 2 inch press connection needs a press tool with the larger jaw or an actuator and press ring for that size, and the 1-1/4 inch branches need their own jaw or ring size. No torch, no flux, and no solder are involved.
6) Is the Viega 15518 tee made in the USA?
No. The 15518 ProPress copper tee is made in Germany. Worth knowing up front on public or institutional work where a domestic-origin requirement is written into the spec.
7) What is the Viega part number and UPC for the 2 x 1-1/4 x 1-1/4 ProPress copper tee?
Viega part number 15518. It is a single configuration, so there is no finish or option to specify when ordering.
8) How heavy is a 2 inch ProPress reducing tee for overhead hanger spacing?
The 15518 weighs 1.153 lbs dry. Add the water column in the 2 inch run when you size hangers and seismic bracing on an overhead line.
