Pps 20738 Propress Xl-c Copper Press Coupling 4 in

Product Description

The PPS 20738 is a 4-inch ProPress XL-C copper press coupling with stop, designed for tool-actuated press connections in demanding mechanical piping systems. Manufactured by Viega and distributed under the PPS BuyLine, this fitting joins copper pipe without open flame, solder, or flux. The press end style creates a watertight, permanent connection rated to 200 psi and a temperature range of 0 to 250 degrees F. The integrated stop positions pipe consistently for repeatable, code-compliant joints. Licensed plumbers and mechanical contractors install this fitting using a compatible press tool and matching jaw or ring for 4-inch copper pipe.

This coupling is suited for a wide range of commercial and residential mechanical systems including potable water distribution, hot and cold water systems, hydronic heating systems, gas systems, fire protection systems, and solar thermal systems. The 4-inch nominal size targets larger-diameter mains and risers common in commercial construction, multi-family residential, and light industrial applications. It is categorized under brass, bronze, and copper press fittings for pipe, tube, and hose fitting assemblies.

Key Features

• Press end style eliminates open flame, solder, and flux for faster, safer installation
• Integrated stop ensures consistent pipe insertion depth for reliable joints
• Rated to 200 psi for high-pressure system confidence
• Temperature range of 0 to 250 degrees F covers both chilled and heating system applications
• Copper construction provides corrosion resistance in potable and hydronic water systems
• 4-inch nominal size serves large-diameter mains and commercial distribution runs

Compatibility

Designed for use in potable water systems, hot and cold water systems, heating systems, gas systems, fire protection systems, and solar systems with 4-inch nominal copper pipe using press end connections.

Installation Notes

Installation must be performed by a licensed plumber or qualified mechanical contractor using a compatible press tool fitted with the correct 4-inch jaw or ring for copper press fittings. Shut off and depressurize the system and drain all water from the affected section before cutting in the fitting. Verify pipe end is clean, deburred, and fully seated against the internal stop before actuating the press tool. Follow all applicable local plumbing codes and ASTM standards for copper press joint systems.
