Nomaco PE21853 Ips Compression Coupling 1-1/4 Inches

Product Description

The NOMACO PE21853 is a 1-1/4-inch IPS compression coupling designed for joining or repairing sections of pipe in plumbing and mechanical systems. Compression couplings in this size range are standard hardware for licensed plumbers and pipefitters working on residential and light commercial installations. The IPS (Iron Pipe Size) designation confirms compatibility with the most common pipe sizing standard used across water supply, HVAC hydronic, and general piping applications. No soldering, threading, or specialized tooling is required for a compression-style connection, making this a practical choice for service and repair work.

The PE21853 suits residential and commercial plumbing repair scenarios where quick, reliable pipe joining is needed on 1-1/4-inch IPS pipe. Typical applications include water supply line repair, hydronic loop connections, and general mechanical piping where a solvent-free or solder-free joining method is preferred. Plumbers and pipefitters working in retrofit or repair situations frequently select compression couplings to minimize disruption to surrounding systems during service calls.

Key Features

• 1-1/4-inch IPS pipe size for compatibility with standard Iron Pipe Size plumbing systems
• Compression-style connection eliminates the need for soldering or threading during installation
• Suitable for repair and joining of existing pipe runs in service and retrofit applications
• Compact coupling form factor for use in confined spaces typical of residential plumbing rough-in

Compatibility

Designed as an OEM-style replacement and repair fitting for 1-1/4-inch IPS pipe systems in residential and light commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the applicable edition of the International Plumbing Code (IPC). Shut off the water supply and depressurize the line before beginning any pipe work. Ensure pipe ends are cut square and deburred before seating into the compression fitting to achieve a proper seal. Do not overtighten the compression nut, as this can distort the ferrule and compromise the connection.
