All-Brass Durability: The 3/8 Tube to 1/8 NPT Connector Advantage

The 3/8 Tube to 1/8 NPT Connector (Automann Part # 177.13B686A) is constructed entirely from high-grade brass, including both the body and the collet. Unlike plastic alternatives, this all-brass design offers superior resistance to road chemicals, vibration, and extreme temperature swings. Note: The "Push-to-Connect" (PLC) mechanism allows technicians to simply push the nylon tubing into the fitting for an instantaneous seal, drastically reducing repair time compared to traditional compression fittings.
