Parker H0C Pneumatic Hose Coupling 1/4 in Mnpt Industrial

Product Description

The PARKER H0C is a male NPT pneumatic hose coupling connector designed for compressed air and pneumatic tool applications. Built to Industrial Interchange standards, this connector features a 1/4-inch body diameter with a 1/8-27 MNPT threaded connection and a maximum working pressure of 300 psi. The body is steel with a zinc chromate finish for corrosion resistance. At 1.56 inches overall length and a 0.5-inch hex size, it is sized for standard pneumatic quick-disconnect setups. Licensed HVAC technicians, pipefitters, and industrial maintenance technicians install this type of fitting where threaded pneumatic connections are required.

This coupling connector is suited for residential and light commercial pneumatic systems, air compressor lines, and pneumatic tool circuits using Industrial Interchange-standard quick-connect components. The 1/8-27 NPT thread size is common in small-bore pneumatic lines and fits standard port sizes found on air tools, regulators, and manifolds. It is sold individually and intended for direct installation into threaded NPT ports.

Key Features

• Industrial Interchange connector type for broad compatibility with standard pneumatic quick-disconnect systems
• 1/8-27 MNPT thread for direct installation into standard NPT-ported equipment
• 300 psi maximum working pressure rated for typical compressed air service
• Steel construction with zinc chromate finish for durability and corrosion resistance
• 1.56-inch overall length and 0.5-inch hex for easy wrench installation in tight spaces

Compatibility

Designed as an OEM-style replacement or new-installation connector for pneumatic systems using Industrial Interchange-standard quick-disconnect couplings with 1/8-27 MNPT threaded ports.

Installation Notes

Installation is performed by qualified pneumatic or mechanical technicians. Depressurize the air line and bleed residual pressure before removing or installing any coupling. Apply thread sealant or PTFE tape to the MNPT threads per standard pneumatic fitting practice; do not overtighten, as steel NPT threads can damage softer port materials. Verify working pressure of the connected system does not exceed the 300 psi rating of this fitting.
