Midland Industries 540608SA 45 Degree Swivel Elbow Brass

Product Description

The MIDLAND INDUSTRIES 540608SA is a 45-degree swivel elbow fitting designed for push-to-connect pneumatic and fluid line applications. It connects a 3/8-inch push-in port to a 1/2-inch male NPTF thread, allowing a directional change in the line while maintaining a leak-free seal. Constructed from brass, this fitting carries a D.O.T. rating and handles pressures up to 150 psi across a temperature range of -40 to 200 degrees F. Plumbers, HVAC technicians, and fleet maintenance professionals install this type of fitting in air brake systems, compressed air lines, and similar pressurized tubing runs.

This swivel elbow is suited for residential and commercial applications where a rigid straight connection is not practical. The push-in end accepts 3/8-inch OD tubing without additional tools, while the 1/2-14 MNPTF threaded end mates to standard port fittings. The D.O.T.-rated construction makes it appropriate for vehicle air brake plumbing as well as stationary compressed air distribution systems. It is typically installed by licensed plumbers, HVAC technicians, or qualified maintenance mechanics working on air and fluid distribution lines.

Compatibility

Designed as an OEM-style push-to-connect replacement fitting for compressed air, pneumatic, and fluid distribution systems requiring a 3/8-inch push-in inlet and a 1/2-inch MNPTF outlet with a 45-degree directional change.

Installation Notes

Shut off and bleed system pressure completely before removing or installing any fitting. Ensure tubing is cut cleanly and squarely and that the OD is free of burrs before inserting into the push-in port. Apply thread sealant appropriate for NPTF connections on the threaded end per the fitting manufacturer and applicable plumbing codes. Inspect the connection for leaks after pressurizing the system.
