Specifications

The AUTOMANN 177.12C64446 PLC Union Tee DOT 1/4 × 1/4 × 3/8 is a critical component designed for modern heavy-duty air brake systems. Its composite body, paired with a brass collet, ensures strong, corrosion-resistant connection in demanding environments. This union tee allows you to merge two 1/4" lines into a 3/8" line (or branch off from 3/8" to 1/4" branches) in tight spaces, maintaining airflow consistency and system integrity. It is rated for DOT service and engineered to withstand vibration, pressure cycles, and thermal stresses. With cross references to Paccar’s G38-6018-040406 / G386018040406, this fitting is widely used in Paccar, Kenworth, and Peterbilt air systems. Wofford Truck Parts stocks it with quality checks and ensures fast shipping so that your air brake repairs or upgrades proceed without downtime.
