Jet 422551 3/8″ Body x 3/8″ NPT Female Type P Automotive Coupler

The Jet Equipment & Tool 422551 Type P automotive coupler is a steel pneumatic fitting designed for fast, secure air connections in automotive, industrial, and shop air systems. This female coupler features a 3/8″ body with a 3/8″ NPT female thread, making it suitable for applications that require a larger threaded connection while maintaining compatibility with standard Type P automotive-style plugs. Manufactured to ANSI T3.20.14 dimensions, it ensures proper fit and consistent engagement across commonly used compressed air setups.

This coupler is equipped with a deep knurled socket sleeve, allowing for a secure grip during coupling and uncoupling, even with gloves or oily hands. The 6-ball positive locking mechanism helps maintain a reliable connection under pressure, reducing the risk of accidental disconnects during tool operation. Constructed from zinc-plated steel, the coupler resists rust and corrosion caused by moisture and daily shop exposure. With a maximum working pressure of 200 PSI and 50 SCFM airflow at 100 PSIG inlet with a 10 PSIG pressure drop, it supports steady air delivery for impact wrenches, ratchets, nailers, and other pneumatic tools. A wide operating temperature range of -40°F to 225°F allows dependable performance in both cold and warm environments. Bulk packaging makes this coupler a practical choice for maintenance departments and high-use shop settings.
