Viega 18473 – Frequently Asked Questions
1) What size copper pipe does the Viega 18473 ProPress reducer connect?
The Viega 18473 is a 1-1/2 inch by 3/4 inch reducer, so it takes a 1-1/2 inch copper line down to 3/4 inch in a single fitting. Both ends are press connections (P1 x P2), so there is no soldering on either side. It is made of copper.
2) Do both ends of the Viega 18473 reducer get pressed, or is one end solder?
Both ends press. The connection type is P1 x P2, meaning press on the large end and press on the small end. You crimp it with press jaws sized for each end, 1-1/2 inch on one side and 3/4 inch on the other, so you need both jaw sizes on hand before you make up the joint.
3) How much room do I need to fit a 1-1/2 x 3/4 ProPress copper reducer in a tight chase?
The 18473 reducer measures 2.122 x 2.122 x 3.327 inches overall. Plan for that footprint plus jaw clearance around the crimp ring on each end, which is usually the limiting factor in a stud bay or tight chase rather than the fitting body itself.
4) Can I use the Viega 18473 on PEX or on steel pipe?
No. The 18473 is a copper press fitting with copper press ends, so it is intended for copper tube systems. For PEX or for carbon steel lines you need the fitting built for that system, not this one.
5) What is the part number and manufacturer for this 1-1/2 x 3/4 press reducer?
It is Viega part number 18473, a ProPress copper reducer in 1-1/2 inch by 3/4 inch. The fitting is made in Germany. Distributors ordering by MPN should use 18473.
