Midland Industries 20860 Swivel Male Branch Tee Composite

Product Description

The MIDLAND INDUSTRIES 20860 is a composite swivel male branch tee fitting designed for pneumatic and fluid distribution systems where a single inlet must branch into two directions while providing a threaded male outlet. The tee connects via 4 mm push-to-connect ports on two ends and exits through a 1/4-inch male BSPT swivel on the third port. The positional swivel feature allows the threaded connection to be oriented after installation without stressing the tubing or the body. Rated to 150 psi and serviceable from 32 to 140 degrees F, this fitting suits compressed air and compatible fluid lines in light industrial, automation, and instrumentation applications. A licensed plumber, pipefitter, or automation technician installs it.

This fitting is commonly used in pneumatic control panels, machine automation assemblies, and process instrumentation lines where metric tubing is routed alongside BSPT-threaded ports. The push-to-connect ends accept 4 mm OD tubing for tool-free insertion and release. The composite body keeps weight minimal, with the complete fitting weighing 0.03 pounds, making it practical in densely packaged enclosures or manifold assemblies where steel or brass fittings would add unnecessary mass.

Key Features

• Positional swivel on the 1/4-inch male BSPT port allows directional adjustment after thread engagement
• Dual 4 mm push-to-connect ports enable tool-free tubing insertion and secure retention
• 150 psi maximum working pressure suitable for standard compressed air service
• Operating temperature range of 32 to 140 degrees F covers most indoor pneumatic environments
• Composite body construction reduces overall fitting weight to 0.03 pounds
• Compact footprint at 1.25 inches wide by 0.9 inches long by 0.55 inches tall fits tight panel layouts

Compatibility

Designed as an OEM-style replacement or new-installation fitting for pneumatic and light fluid systems using 4 mm OD metric tubing and 1/4-inch BSPT male threaded ports.

Installation Notes

Installation is typically performed by a licensed pipefitter, pneumatic technician, or instrumentation technician. Depressurize and isolate the system fully before removing any existing fittings or inserting tubing into the push-to-connect ports. Ensure tubing ends are cut cleanly and squarely for proper sealing inside the collet mechanism. The BSPT swivel thread is a tapered parallel-style thread - verify port compatibility before engaging to avoid cross-threading or improper seal.
