Mueller Streamline CAP00863 Wrot Copper Cap 3/4 in

Product Description

The MUELLER STREAMLINE CAP00863 is a wrot copper flush cap designed to terminate 3/4-inch copper tubing using a sweat solder connection. This fitting is manufactured from wrot copper, which offers superior grain structure and pressure integrity compared to cast fittings. It is used to permanently close the end of a copper line in residential and commercial plumbing, HVAC, and refrigeration piping systems. The cap measures 0.714 inches in width and 2.313 inches in height and depth, making it a compact, low-profile solution for dead-end piping situations. Licensed plumbers and HVAC technicians are the typical installers.

This cap is suited for sweat-soldered copper piping systems in residential and light commercial applications, including potable water distribution, hydronic heating, and HVAC refrigerant or condensate line termination. It meets multiple ASME and NSF standards, making it appropriate for use in systems that require certified fittings for potable water or pressure service. No specific model exclusions apply; the fitting is appropriate wherever a 3/4-inch sweat end cap is called for in a copper piping system.

Compatibility

Designed as an OEM-style sweat solder end cap for 3/4-inch copper tubing systems in plumbing, HVAC, and refrigeration applications where a certified copper flush cap is required.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician using standard sweat soldering tools including a torch, lead-free solder, and flux. Shut off water supply and depressurize and drain the line before soldering. Follow local plumbing codes and ASME B1.20.1 threading and fitting standards as applicable. Do not apply heat to a pressurized or wet line.
