ProPress XL Reducer 20813

The Viega ProPress XL reducer 20813 is a straight reducing adapter made of copper with an EPDM O-ring. It connects a 2-1/2 inch copper tube size on the FTG side to a 1-1/2 inch copper tube size on the press-fit side for potable water applications. The fitting has an overall length of 4 27/32 in.

Installers needing a press-fit transition

This reducer suits plumbers joining dissimilar copper tube diameters in potable water systems using the ProPress XL press-fit method. It is not for installers who require threaded, soldered or push-fit connections instead of a press joint. Buyers needing a different diameter combination or a flange connection should look at alternative fittings.

Press-tool installation with standard checks

Installation is completed with a compatible ProPress XL press tool and jaw set, creating a permanent mechanical joint without flame or solder. Common issues include using the wrong jaw size for the 2-1/2 inch or 1-1/2 inch ends, skipping the O-ring inspection, or pressing on tubing that is not cut square and deburred. The fitting is rated for 200 psi maximum operating pressure and 250 Degrees F maximum operating temperature.
