Nibco PRESCAP34-JAR Copper Press Tube Cap 3/4 in 20 Pack

Product Description

The NIBCO PRESCAP34-JAR is a copper press tube cap designed to terminate open 3/4-inch copper press-fit piping systems. This fitting uses a press-style connection — no soldering, no open flame — making it a fast and reliable option for capping live or newly installed lines. It ships in a 20-count jar, suited for service contractors and plumbing professionals who need to keep quantity stock on hand for residential and light commercial work. The press-fit design seats against compatible press tools and jaws to form a watertight, permanent seal in seconds.

This cap is intended for use in copper press-fit potable water, hydronic heating, and cooling piping systems where 3/4-inch tube termination is required. The 20-pack jar format makes it practical for van stock or shop inventory on projects that involve multiple cap-off points. It is installed by licensed plumbers and pipefitters working on new construction, renovation, or repair applications where torch-free connections are preferred or required.

Key Features

• Press-fit connection — no soldering or open flame required

Compatibility

Designed as an OEM-style press fitting for use with standard 3/4-inch copper press-fit piping systems using compatible press tools and jaw sets.

Installation Notes

Installation requires a compatible press tool and the correct 3/4-inch jaw or ring for copper press fittings. Shut off and depressurize the line before pressing, and verify the pipe end is clean, round, and free of burrs or debris prior to seating the fitting. Press fittings should be installed in accordance with local plumbing codes and the fitting manufacturer specifications. Unpressed fittings are not watertight and must be pressed before the system is returned to service.
