Parker H3E-F Pneumatic Coupling 3/8 in Body Industrial

Product Description

The PARKER H3E-F is a female connector-style pneumatic hose coupling designed for use in compressed air and industrial fluid systems. It features a 3/8 inch body diameter with a 1/2-14 Female NPTF threaded connection, providing a pressure-tight mechanical seal without the need for thread sealant tape in most applications. Rated to 300 psi maximum working pressure, this coupling is built from steel with a zinc chromate finish for corrosion resistance. At 1.84 inches overall length and 0.1394 pounds, it is a compact, durable connection point suited to industrial pneumatic lines.

This coupling follows the Industrial Interchange standard, making it compatible with the broad installed base of Industrial Interchange pneumatic quick-disconnect systems found in manufacturing, assembly, and maintenance environments. It is typically used in shop air systems, pneumatic tool lines, and process air circuits where reliable threaded connections are required. The threaded connector design makes it appropriate for permanent or semi-permanent plumbing into manifolds, fittings, or tool inlets.

Key Features

• Industrial Interchange coupling type for wide cross-compatibility with standard shop air equipment
• Female NPTF thread at 1/2-14 for a pressure-tight seal in pneumatic service
• 300 psi maximum working pressure rating
• Steel construction with zinc chromate finish for corrosion resistance
• Compact 1.84 inch overall length suits tight installation spaces
• 1.0 inch hex size for standard wrench installation

Compatibility

Designed as an Industrial Interchange standard connector for use in pneumatic systems requiring a 1/2-14 Female NPTF threaded coupling with a 3/8 inch body diameter.

Installation Notes

Installation is performed by a licensed pipefitter, pneumatic technician, or qualified maintenance mechanic. Depressurize and lock out the compressed air system before removing or installing any coupling. Use an appropriately sized wrench on the 1.0 inch hex to achieve a secure, leak-free connection without over-tightening. Follow applicable OSHA and local safety codes for compressed air piping.
