Overview
The 3/8 Tube M12 PLC Elbow from Automann is a high-performance pneumatic fitting designed for precision air line routing in heavy-duty truck systems. Specifically engineered for modern air brake and suspension setups, this fitting features a metric M12 x 1.5 O-ring thread on one side and a 3/8" Push-to-Connect (PLC) tube port on the other. Its 45-degree angled swivel design is the perfect solution for tight engine bays or chassis spaces where a standard straight fitting would cause hose kinking or unnecessary stress.
Secure, Leak-Proof Sealing: The 3/8 Tube M12 PLC Elbow Advantage
Reliability is critical in Class 8 air systems, which is why this 3/8 Tube M12 PLC Elbow is equipped with a high-grade O-ring seal to ensure an airtight connection at the manifold. The swivel feature allows for exact orientation of the 3/8" nylon tubing during installation, making the process fast and stress-free. Note: Constructed by Automann to withstand high vibration and extreme under-chassis temperatures, this elbow ensures your air signal remains consistent throughout the long haul.
As we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize precision-engineered fittings that meet factory standards. This 3/8 Tube M12 PLC Elbow (Part # 177.12C746M12) serves as a direct professional-grade replacement for Freightliner 23-14559-003 and 2314559003. Simply push your 3/8" nylon air line into the PLC port for a secure, "bite-style" grip that won't release under high pressure.
