5/16 in. x 1/4 in. Composite Stainless Steel Swivel Male Elbow

Overview

The Midland 20538SS is a 90-degree swivel male elbow joining a 5/16 in. push-to-connect tube port to a 1/4 in. male NPT thread. Machined from 316 stainless steel, it delivers superior corrosion resistance for washdown, marine, and chemical-handling lines where brass will not survive. The swivel body lets you orient tubing after the thread is tight.

Frequently Asked Questions

Does the elbow swivel after installation?
Yes. Tighten the NPT thread to spec, then rotate the body to aim the tube port where you need it.

What tubing does the 5/16 in. port accept?
It accepts 5/16 in. OD tubing rated for your pressure and temperature; nylon, polyurethane, and polyethylene are common.

Why choose stainless over brass here?
316 stainless resists chlorides and washdown chemicals that pit and dezincify brass, making it the right choice for marine and sanitary service.
