Midland Industries 77637LF 90 Degree Copper Elbow 1-1/2 in

Product Description

The MIDLAND INDUSTRIES 77637LF is a 90-degree male elbow fitting designed for copper sweat plumbing systems. It connects a 1-1/2 inch copper sweat (C) end to a 1-1/2 inch male pipe thread (MPT) end, allowing a direction change while transitioning to a threaded connection in a single fitting. Weighing 0.83 pounds, this elbow is built from copper, which provides reliable corrosion resistance and long service life in potable water and hydronic applications. Licensed plumbers and pipefitters install this fitting in residential and light commercial systems where a sweat-to-threaded 90-degree turn is required.

This fitting is suited for use in residential and commercial plumbing installations where copper sweat lines meet threaded pipe connections. Common applications include supply line transitions, water service connections, and hydronic heating distribution systems. The 1-1/2 inch sizing fits standard copper tube in that diameter, making it a straightforward replacement or new-installation fitting for any job requiring a 90-degree change of direction with a sweat inlet and a male threaded outlet.

Key Features

• 90-degree elbow geometry for direction changes in copper sweat systems
• 1-1/2 inch C (copper sweat) inlet for soldered connections
• 1-1/2 inch MPT (male pipe thread) outlet for threaded transitions
• Copper construction for corrosion resistance and long service life
• Compact, single-fitting solution combining a direction change and a sweat-to-thread transition

Compatibility

Designed as an OEM-style replacement or new-install fitting for plumbing systems using 1-1/2 inch copper sweat pipe with a male threaded outlet connection.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and fully depressurize and drain the line before cutting or soldering. Clean and flux all sweat surfaces before applying heat, and apply thread sealant or PTFE tape to the MPT threads before making the threaded connection. Allow soldered joints to cool fully before restoring pressure.
