Mueller Industries 15716 Wrot Copper Pipe Cap 1/8 in

Product Description

The MUELLER INDUSTRIES 15716 is a wrot copper pipe cap designed to seal the end of a 1/8-inch copper pipe or fitting in sweat (solder) connection applications. Manufactured from wrot copper, this cap provides a reliable, pressure-rated termination point on copper piping systems used in plumbing, HVAC, refrigeration, and mechanical systems. The C-type end connection means it is installed using a standard sweat-solder process, making it a straightforward component for licensed plumbers and HVAC technicians working on copper distribution lines. The outside diameter measures 1/4 inch. Sold in a package of 10 units.

This cap is suited for use in residential and light commercial plumbing, HVAC, and refrigeration piping where copper tube runs require capping during pressure testing, system modification, or permanent line termination. It is appropriate for tight-space applications given the compact 1/8-inch fitting size. Plumbers and HVAC techs routinely use caps like this one during rough-in work, pressure testing, and system isolation procedures.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians using standard soldering equipment, flux, and lead-free solder in accordance with IPC and local plumbing codes. Shut off and depressurize the system and ensure the pipe end is clean, dry, and deburred before fitting the cap and applying heat. Do not overheat the fitting, as excessive heat can damage adjacent components or compromise the solder joint. Follow all applicable local code requirements for material and solder type.
