Nibco PRESCAP1 Press Tube Cap 1 Inch Copper

Product Description

The NIBCO PRESCAP1 is a 1-inch copper press tube cap designed to terminate or seal the end of a copper press system piping run. It connects without solder, open flame, or flux, using a press-fit mechanism that compresses a pre-installed elastomeric sealing element when crimped with a compatible press tool. Plumbers and pipefitters use this cap on potable water, hydronic heating, and cooling distribution systems where press-fit connections are specified. Its all-copper construction suits both exposed and concealed piping installations.

This cap is suited for residential and light commercial plumbing and hydronic applications. It is typically installed at the end of a branch line, to cap an unused outlet, or to pressure-test a section of copper press piping before final connection. Press-fit fittings reduce labor time compared to soldered joints, making them common in occupied-space renovations and retrofits where open flame is restricted.

Key Features

• Press-fit connection eliminates the need for soldering, brazing, or flux
• 1-inch nominal size fits standard copper press system tubing
• All-copper construction for corrosion resistance in water and hydronic systems
• Pre-installed sealing element enables fast, repeatable crimped joints
• Suitable for potable water, hydronic heating, and cooling distribution piping

Compatibility

Designed as an OEM-style press-fit replacement cap compatible with 1-inch copper press piping systems.

Installation Notes

Installation requires a calibrated press tool with the correct jaw size for 1-inch press fittings. Shut off and depressurize the water or hydronic system before working on the piping. Verify the pipe end is clean, cut square, and free of burrs before seating the cap. Follow local plumbing code requirements, including IPC or applicable state amendments, for press-fit fitting use in your jurisdiction.
