Anderson Metals Corp 710081-04 Compression Cap 1/4 Inch

Product Description

The ANDERSON METALS CORP 710081-04 is a 1/4-inch compression cap designed to terminate an open compression fitting or copper tubing end. The cap threads onto a standard compression nut and ferrule assembly, sealing the line without soldering or special tools. It is lead free compliant and meets the requirements of Public Law 111-380, making it suitable for potable water and plumbing applications where lead-free materials are mandated. Plumbers and HVAC technicians reach for compression caps when capping an unused branch, decommissioning a line, or pressure-testing a run before final connection.

This cap is used in residential and light commercial plumbing systems on 1/4-inch copper or compatible tubing. Common install scenarios include capping refrigeration or water supply lines, sealing off unused ports on manifolds, and temporary line isolation during repairs. The part is sold in packages of 10, making it practical for service trucks and supply stock.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC technician. Shut off the water supply or isolate the refrigerant circuit and relieve system pressure before fitting the cap. Hand-tighten the compression cap onto the ferrule and nut, then snug with a wrench — do not overtighten, as over-compression can deform the ferrule and cause leaks. Verify a leak-free seal by pressure-testing the line after installation per applicable IPC or local plumbing code requirements.
