Midland Industries 77122 90 Deg Short Elbow 8 in Copper

Product Description

The MIDLAND INDUSTRIES 77122 is a 90-degree short elbow fitting designed for copper sweat (solder) connections. It accepts 8-inch tube OD on both ends, making it a symmetrical fitting suited for directional changes in large-diameter copper piping systems. At 27.57 pounds, this is a heavy-duty fitting built for demanding commercial and industrial plumbing or HVAC hydronic applications. Licensed plumbers and pipefitters are the primary installers. The short-radius elbow geometry reduces overall installed length compared to a long-radius elbow, which is an advantage in tight mechanical rooms or congested pipe runs.

This fitting is used in large-diameter copper piping systems where a 90-degree change of direction is required. Typical applications include commercial HVAC chilled water and condenser water distribution, large-scale hydronic heating systems, and industrial process piping. The 8-inch tube OD size places this fitting firmly in the commercial and industrial tier, where copper sweat connections are specified for corrosion resistance and long service life. Installation is performed by journeyman or master plumbers and pipefitters familiar with large-bore copper soldering or brazing procedures.

Key Features

• 90-degree short elbow geometry for compact directional changes in large pipe runs
• 8-inch tube OD on both connections for symmetrical, same-size installation
• Copper material provides corrosion resistance suitable for water and HVAC hydronic service
• Copper sweat (solder or braze) connection type for a secure, leak-resistant joint
• Substantial construction at 27.57 pounds, appropriate for commercial and industrial service

Compatibility

Designed as an OEM-style copper sweat fitting for large-diameter commercial and industrial piping systems requiring 8-inch tube OD connections at a 90-degree angle.

Installation Notes

Installation of large-bore copper sweat fittings should be performed by a licensed plumber or pipefitter experienced with commercial copper brazing procedures. The system must be fully depressurized, drained, and dried before fitting is soldered or brazed into place; moisture in the pipe will prevent a sound joint. Applicable codes include the International Plumbing Code and local mechanical codes governing large-diameter copper piping. Use appropriate flux, filler metal, and heat source rated for the pipe diameter and service conditions.
