Nibco PRESCAP114 Copper Press Tube Cap 1-1/4 in

Product Description

The NIBCO PRESCAP114 is a copper press tube cap designed to terminate or seal the end of a 1-1/4 inch copper press-fit piping system. The press-style connection eliminates the need for soldering or open flame, allowing installation with a standard press tool in occupied or flame-restricted spaces. This fitting is suited for potable water, hydronic heating, and mechanical piping systems where a clean, permanent end cap is required. Licensed plumbers and pipefitters working on commercial or residential systems are the primary installers.

The PRESCAP114 is used in press-fit copper piping systems requiring a capped termination point on 1-1/4 inch tube ends. Typical applications include capping off unused branch lines, temporary or permanent service shutoffs on distribution headers, and terminations in tight mechanical rooms where torch access is limited or prohibited. It is appropriate for both new construction and retrofit work on hydronic and domestic water systems.

Key Features

• Press-fit connection requires no soldering, brazing, or open flame
• 1-1/4 inch size for standard copper tube terminations
• Copper construction provides corrosion resistance in water and hydronic applications
• Permanent, leak-tight seal when installed with a compatible press tool
• Suitable for use in flame-restricted or occupied building spaces

Compatibility

Designed as an OEM-style press fitting compatible with 1-1/4 inch copper press-fit piping systems. Verify jaw and ring compatibility with your specific press tool manufacturer before installation.

Installation Notes

Installation requires a calibrated press tool fitted with the correct jaw size for 1-1/4 inch copper press fittings. Shut off and depressurize the piping system before fitting installation. Ensure the tube end is clean, round, and free of burrs before insertion to achieve a proper seal. Work must comply with applicable local plumbing codes, which may reference IPC or IFGC standards depending on jurisdiction.
