Nomaco PESF90L1 Socket Fusion 90 Degree Elbow 1 Inch Ips

Product Description

The NOMACO PESF90L1 is a 1-inch IPS socket fusion 90-degree elbow designed for use in polyethylene piping systems. This fitting creates a right-angle directional change in a pipeline and is joined to pipe using a socket fusion process, which involves heating mating surfaces and pressing them together to form a continuous, leak-resistant bond. It is sized for 1-inch IPS (Iron Pipe Size) pipe and is suited for potable water, geothermal, and general fluid distribution applications. Installation is typically performed by licensed plumbers or pipefitters trained in thermoplastic fusion joining.

This elbow is used in residential and light commercial piping runs where a 90-degree change in flow direction is needed. Socket fusion fittings are common in underground and above-ground PE pipe systems, including water service lines and hydronic distribution loops. The IPS sizing standard makes this fitting compatible with pipe manufactured to standard IPS outside diameter specifications.

Key Features

• 90-degree elbow geometry for right-angle directional changes in piping runs
• Socket fusion end connections for a heat-fused, monolithic joint
• 1-inch IPS sizing for standard iron pipe size compatibility
• Suitable for potable water, geothermal, and fluid distribution systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch IPS polyethylene pipe systems using socket fusion joining methods.

Installation Notes

Socket fusion fittings must be installed by a technician trained and qualified in thermoplastic fusion procedures. Both the pipe end and fitting socket must be cut square, cleaned, and brought to the correct fusion temperature using calibrated fusion tools before joining. Do not use solvent cement or mechanical clamps in place of the socket fusion process. Follow applicable codes including ASTM and local plumbing authority requirements for thermoplastic pipe installation.
