Midland Industries 20165C 3/8 in Composite Swivel Run Tee

Product Description

The MIDLAND INDUSTRIES 20165C is a composite swivel run tee fitting designed for push-to-connect and threaded plumbing connections in fluid distribution systems. It features three ports: two 3/8-inch push-to-connect ends and one 3/8-inch male NPT swivel connection at the branch. The positional swivel allows the male NPT port to be rotated for alignment without disturbing the run connections, making installation faster and more flexible. Rated to 150 psi and suitable for operating temperatures from 32 degrees F to 140 degrees F, this fitting is appropriate for potable water, compressed air, and similar low-pressure fluid lines. Licensed plumbers and HVAC technicians are the primary installers.

The 20165C is used in residential and light commercial plumbing, pneumatic, and HVAC applications where a tee connection must transition between push-to-connect tubing and a male NPT threaded port. Its composite body keeps weight low at 0.08 pounds while maintaining a rated working pressure of 150 psi. The compact form factor, measuring 2.5 inches in length and 1.45 inches in width, fits in tight spaces common to equipment installations and panel rough-ins. The 3/8-18 NPT thread on the swivel port matches standard male NPT fittings used throughout trade plumbing work.

Key Features

• Positional swivel on the male NPT branch port allows rotational alignment without loosening run connections
• Push-to-connect ends accept 3/8-inch OD tubing for tool-free, no-solder connections
• Composite body construction reduces weight while resisting corrosion
• Rated to 150 psi working pressure for low-pressure fluid and air systems
• Operating temperature range of 32 degrees F to 140 degrees F
• 3/8-18 male NPT thread on swivel port for compatibility with standard threaded fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 3/8-inch OD push-to-connect tubing and 3/8-inch male NPT threaded connections in plumbing, HVAC, and pneumatic distribution lines.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off the water or air supply and depressurize the line completely before making or breaking any connections. Push-to-connect ends require clean, square-cut tubing inserted fully until it seats; always verify tubing is fully engaged before restoring pressure. Ensure the NPT swivel port is threaded into the mating fitting to a hand-tight plus wrench-tight seal using appropriate thread sealant or PTFE tape per applicable plumbing codes.
