SKU CH-P35D-K1TQE

A copper ProPress XL reducer joins 4-inch and 3-inch tubing with a street-to-press connection rated to 200 psi and 250 °F

  • Reduces pipe diameter from 4 in to 3 in
  • Press connection installs without soldering or threading
  • Copper construction resists corrosion in plumbing systems
  • Rated for 200 psi working pressure
  • Operates from 0 to 250 degrees F

Copper XL reducer for large-bore piping

The Viega ProPress XL reducer joins 4-inch and 3-inch copper tube using a street-by-press connection. It is rated for 200 psi and a temperature range of 0 to 250 degrees F. The fitting carries part number 20783 and is supplied new.

Street-by-press design changes installation

The street end slides into a standard fitting while the press end accepts a ProPress jaw, removing the need for threading or soldering on the larger diameter. This cuts joint time and avoids open flame on 4-inch copper.

Suited for commercial hydronic and potable systems

Installers working on high-capacity water or heating loops up to the rated pressure and temperature will find the reducer matches the spec. Projects requiring smaller tube sizes, different materials or a press-by-press configuration should select another fitting.

Questions about this item

Does the copper ProPress XL reducer 20783 need periodic re-pressing or seal replacement after installation?

The press connection creates a permanent mechanical joint; no re-pressing or seal replacement is required once the fitting is properly installed.

What pressure or temperature limit will be reached first if this reducer runs continuously at high load?

The reducer is rated for 200 psi maximum pressure and a temperature range up to 250 degrees F; whichever limit is reached first in your system will govern safe operation.

How much heat does the fitting itself generate when hot water circulates through it all day?

The copper fitting does not generate heat; it simply conducts the fluid temperature, so its surface will approach the water temperature up to the 250 degrees F rating.
