Nibco PRESCOUP114 1-1/4 in Copper Press X Press Coupling

Product Description

The NIBCO PRESCOUP114 is a copper press-style coupling with an integrated stop, designed for joining 1-1/4 inch copper tubing in pressurized plumbing and hydronic systems. The press connection method eliminates open-flame soldering, allowing techs to make secure, leak-tested joints using a compatible press tool. The built-in stop positions pipe ends consistently, ensuring full insertion depth before pressing. This fitting is suited for licensed plumbers and mechanical contractors working on water distribution, radiant heating, or hydronic piping where flame-free installation is preferred or required.

This coupling is intended for residential and light commercial plumbing applications where 1-1/4 inch copper lines are joined or extended. Typical install scenarios include domestic water supply repairs, hydronic heating loops, and mechanical room piping. The press-fit design is especially useful in occupied buildings or areas where torch use is restricted by code or fire safety requirements.

Key Features

• Press x Press end connections for flame-free, no-solder installation
• Integrated coupling stop ensures consistent pipe insertion depth
• 1-1/4 inch nominal size fits standard copper tubing
• Copper construction provides corrosion resistance in potable water and hydronic systems
• Compatible with standard press tooling used in press-fit copper systems

Compatibility

Designed as an OEM-style press fitting for use with 1-1/4 inch copper tubing in standard press-fit copper piping systems.

Installation Notes

Installation requires a calibrated press tool with the appropriate copper press jaw for 1-1/4 inch fittings. Shut off and depressurize the water or hydronic system before cutting into the line. Clean and deburr all pipe ends before insertion to ensure a proper seal. Work must comply with local plumbing codes, which typically reference IPC or equivalent standards for press-fit copper fittings.
