Parker H1E Pneumatic Hose Coupling 1/4-18 Nptf 3/8 in

Product Description

The PARKER H1E is a threaded pneumatic hose coupling connector designed for compressed air and pneumatic fluid power systems. Built to the Industrial Interchange standard, this connector mates with a wide range of compatible couplers used in shop air, pneumatic tooling, and industrial automation lines. It features a 1/4-18 Female NPTF thread for a pressure-tight connection and a 3/8-inch body diameter. Constructed from steel with a zinc chromate finish for corrosion resistance, the H1E is rated to 300 psi maximum working pressure. Licensed HVAC technicians, industrial maintenance mechanics, and plumbing professionals install this type of fitting during system assembly and service work.

The H1E is suited for residential shop air setups, light industrial pneumatic tool lines, and commercial compressed air distribution systems requiring a reliable quick-connect entry point. The Industrial Interchange design ensures broad cross-brand compatibility with standard shop air accessories. With an overall length of 1.6 inches and a 0.62-inch hex size, it fits standard wrenches and installs cleanly into existing threaded ports without modification.

Installation Notes

Installation should be performed by a qualified mechanic or pipefitter familiar with compressed air systems. Depressurize and lock out the air supply before removing or installing any pneumatic fitting. Apply thread sealant appropriate for pneumatic service to the NPTF threads and tighten to snug using a wrench on the hex flats — do not over-torque. Verify the system holds rated pressure and check for leaks before returning to service.
