Overview
Optimize your air line routing in tight spaces with the 3/8 x 1/4 PLC Swivel Elbow by Automann. This professional-grade air fitting features a 45-degree angle, making it the ideal solution for connecting 3/8" DOT nylon tubing to 1/4" NPT ports where a standard straight or 90-degree fitting would cause line kinking. Whether you are plumbing air valves on the driver side or securing suspension lines on the passenger side, this fitting provides the flexibility and reliability your chassis demands.
Precision Routing: The 3/8 x 1/4 PLC Swivel Elbow Advantage
The 3/8 x 1/4 PLC Swivel Elbow (Automann Part # 177.12C746B) is engineered with a high-strength composite body and a precision brass collet for maximum durability. The integrated swivel base allows the fitting to be tightened into the port first, after which the body can be rotated 360 degrees to perfectly align with the incoming air line. Note: Featuring Push-Lock Connect (PLC) technology, this fitting allows for instant, tool-free installation of 3/8" tubing, significantly reducing maintenance time and labor costs.
As we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize DOT-compliant components that stand up to the high-vibration environment of the road. This 3/8 x 1/4 PLC Swivel Elbow is a direct professional-grade replacement for Parker 379PTC64, Alkon QL13746B, and Weatherhead S754PMT64. The composite body offers excellent resistance to vibration fatigue and road chemicals, ensuring a leak-free seal for the long haul.
