Brass Push-to-Connect (PLC) Swivel Male Elbow - 1/4" Tube x 1/4" NPT 90 Degree - Eaton 1869X4X4S Tectran PL13694B 177.13B694B

Terminate a nylon air line cleanly against a valve or bracket with this Brass PLC Swivel Male Elbow distributed by FleetPro Parts & Tires. It turns 1/4 in tube OD nylon air-brake tubing through a 90 degree bend into a 1/4 in male NPT port, which is what you need when the component sits flush and a straight fitting would force the tube into a hard bend. Kinked tubing and cracked, weeping fittings are the quiet killers of an air system: the leak is small enough to ignore for weeks and expensive enough that the compressor runs its life out trying to keep up. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

A Clean 90 Without a Kink: The Swivel Male Elbow Advantage

The swivel is the whole point. On a fixed elbow you get whatever angle the thread lands on when it tightens, and the usual fix is to twist the tube or back the thread off — both of which cost you the seal eventually. Here the 1/4 in male NPT thread seats properly and the elbow then rotates to line up the tube run, so the nylon leaves the fitting relaxed and stays that way through every heat cycle and every chassis flex.

This is a DOT push-to-connect fitting for nylon air-brake tubing, built in brass so it does not corrode into the port and turn a five-minute job into a drilling operation two winters from now. The tube pushes straight in and locks, so a repair at a truck stop needs nothing beyond a square cut and a firm shove.
