Uponor Q4761250 Propex 90 Degree Elbow 1-1/4 in

Product Description

The UPONOR Q4761250 is a 90-degree elbow fitting designed for use with ProPEX expansion-style PEX piping systems. Manufactured from modified polyphenylsulfone (PPSU), this fitting delivers high heat and chemical resistance suited to demanding plumbing and hydronic distribution applications. At 1-1/4 inches, it accommodates larger-diameter runs where flow capacity and pressure retention matter. Licensed plumbers and mechanical contractors install this fitting using a ProPEX expansion tool and the corresponding PEX-a ring to form a leak-resistant connection without solvents, solder, or open flame.

This elbow is intended for residential and light commercial plumbing installations where directional changes in PEX-a piping are required. Typical applications include domestic hot and cold water distribution, radiant heating supply and return lines, and in-wall or under-slab piping runs. The 90-degree angle allows layout changes in tight spaces without the need for additional offset fittings. It is manufactured domestically, making it suitable for projects with domestic-content procurement requirements.

Key Features

• 90-degree elbow configuration for directional changes in ProPEX piping layouts
• Modified polyphenylsulfone (PPSU) construction provides high temperature and chemical resistance
• 1-1/4 inch size accommodates higher-flow distribution lines
• ProPEX expansion connection eliminates soldering, crimping, or gluing
• Domestically manufactured for projects with domestic-content compliance needs

Compatibility

Designed for use with ProPEX expansion-style PEX-a piping systems and compatible 1-1/4 inch ProPEX expansion rings and tools.

Installation Notes

Installation requires a calibrated ProPEX expansion tool and the appropriate 1-1/4 inch PPSU or PEX-a expansion ring. Shut off the water supply and depressurize the line before cutting or fitting. Follow local plumbing codes, including applicable IPC requirements, for support spacing, pressure ratings, and approved materials. Allow the fitting connection to recover fully after expansion before pressurizing the system.
