ProPress XL 3" x 1-1/2" Reducer

This Viega ProPress XL reducer joins 3-inch and 1-1/2-inch copper tubing in potable-water systems. It uses a straight reducing adapter with a press-fit connection on one side and a fitting-end connection on the other. The copper body and EPDM O-ring suit domestic water service. Model 20818 is supplied new.

Verify tube sizes and press-tool access

Confirm the existing copper tubing matches the 3-inch and 1-1/2-inch copper tube sizes before ordering. Ensure a compatible ProPress XL press tool and jaw set are available for the larger diameter. Check that the 5 11/32-inch overall length fits the layout and that no threading or soldering is required at either joint.

Rated for 200 psi and 250 °F continuous service

The fitting withstands a maximum operating pressure of 200 psi and a maximum operating temperature of 250 degrees Fahrenheit under sustained load. The EPDM seal maintains integrity during prolonged hot-water circulation. Copper construction resists corrosion and scaling in continuous potable-water applications.

Questions about this item

Does the Viega ProPress XL reducer 20818 come with the press tool and copper tubing, or must they be purchased separately?

The fitting is supplied as a single copper reducer with an EPDM O-ring installed. A compatible ProPress XL press tool and the two lengths of 3 in and 1-1/2 in copper tube are not included and must be sourced separately.

When should I choose the 3 in by 1-1/2 in size instead of another ProPress XL reducer?

Select this reducer when the system requires a straight transition from a 3 in copper tube on the FTG side to a 1-1/2 in copper tube on the press-fit side. Other diameter combinations are different part numbers.

What does the 200 psi rating mean once the reducer is pressed into a potable water line?

The joint is rated to hold 200 psi at temperatures up to 250 Degrees F, so it meets typical municipal supply pressures and hot-water circulation temperatures without additional reinforcement.
