Midland Industries SS1502-16-16 90 Deg Swivel Elbow

Product Description

The MIDLAND INDUSTRIES SS1502-16-16 is a 90-degree swivel elbow fitting designed for high-pressure, high-temperature pipe connections. It connects a 1-inch Female NPTF port to a 1-inch Female NPSM swivel port, allowing directional adjustment during assembly without disturbing the seal. Constructed from 316 stainless steel, it is rated for a maximum operating pressure of 4400 psig and temperatures up to 1000 degrees F. This fitting is installed by licensed plumbers, pipefitters, and industrial maintenance technicians working on fluid and gas systems where corrosion resistance and pressure integrity are critical.

This swivel elbow is suited for industrial, commercial, and heavy-duty process piping applications where a fixed-angle elbow would create alignment challenges. The NPSM swivel connection allows rotation during makeup, reducing stress on adjacent fittings and mating components. It is appropriate for use in hydraulic, pneumatic, steam, and chemical fluid systems that demand stainless steel construction for corrosion resistance and elevated temperature service.

Installation Notes

Installation should be performed by a qualified pipefitter or licensed plumber in accordance with applicable mechanical codes. Depressurize and isolate the system completely before removing or installing any fittings. Verify that mating thread types and sizes are compatible before makeup to avoid cross-threading or seal failure. Do not overtighten the NPSM swivel connection, as the swivel feature relies on proper rotational freedom to function correctly.
