Midland Industries 20689 Swivel Male Branch Tee

Product Description

The MIDLAND INDUSTRIES 20689 is a composite-body swivel male branch tee designed for push-to-connect pneumatic and fluid-transfer plumbing systems. It features two 12 mm push-to-connect ports and a 1/2-inch male BSPT swivel outlet, allowing branch connections without rotating the tubing or adjacent fittings. The composite body is nickel-plated for corrosion resistance. The positional swivel on the male BSPT end provides rotational adjustment during installation, making it practical in tight or awkward installations. Rated to 150 psi and suitable for operating temperatures from 32 degrees F to 140 degrees F, this fitting suits a range of light-industrial and trade plumbing applications.

The 20689 is suited for residential and light-commercial installations where metric push-to-connect tubing meets BSPT-threaded equipment or manifolds. Common applications include compressed-air distribution, pneumatic control circuits, and fluid-handling lines that require a branch tee with a swivel male thread outlet. It is typically installed by plumbers, pipefitters, or HVAC technicians working with metric push-to-connect systems alongside BSPT-ported equipment.

Key Features

• Positional swivel on the 1/2-inch male BSPT outlet allows rotational adjustment without disturbing connected tubing
• Two 12 mm push-to-connect ports accept metric tubing without additional tools or ferrules
• Composite body with nickel plating provides corrosion resistance in wet or humid environments
• Rated to 150 psi for reliable performance in compressed-air and fluid-transfer applications
• Operating temperature range of 32 degrees F to 140 degrees F suits most indoor trade installations
• 1/2-14 thread specification on the BSPT swivel end ensures proper engagement with standard BSPT-ported components

Compatibility

Designed for use with 12 mm push-to-connect tubing on two ports and 1/2-inch BSPT-threaded equipment on the swivel outlet. Suitable as an OEM-style or replacement branch tee fitting in composite push-to-connect plumbing and pneumatic systems using metric tubing.

Installation Notes

Depressurize and de-energize the system completely before disconnecting or installing any fittings. Push-to-connect ports require clean, square-cut tubing ends seated fully to the depth stop for a leak-free connection. The BSPT swivel end should be threaded into the mating port with appropriate thread sealant per the equipment manufacturer's recommendation before final positional adjustment. Verify all connections hold rated pressure with a system leak test before returning the line to service.
