Parker H5E Pneumatic Hose Coupling 3/8 Inch

Product Description

The PARKER H5E is a steel pneumatic hose coupling designed for compressed air and pneumatic system connections in industrial and light commercial applications. This connector-style fitting uses a hose barb thread type and features a 3/8 inch body diameter with a 3/8 inch hose inside diameter, making it a direct-fit solution for standard pneumatic hose lines. The zinc chromate finish provides corrosion resistance in shop and field environments. With a maximum working pressure rating of 300 psi, the H5E handles typical shop-air and pneumatic tool service demands. Installation requires no special tooling beyond standard hose clamp and barb-fitting practices familiar to any service technician.

The H5E follows Industrial Interchange standards, making it compatible with the broad range of pneumatic equipment and hose assemblies built to that specification. It is suited for use in manufacturing facilities, service garages, construction sites, and HVAC mechanical rooms where compressed air distribution lines require reliable hose-to-coupling connections. The hose barb design allows quick, secure attachment to 3/8 inch ID pneumatic hose without threaded pipe connections.

Key Features

• Industrial Interchange coupling type for broad pneumatic system compatibility
• 3/8 inch body diameter and 3/8 inch hose inside diameter for standard pneumatic hose lines
• 300 psi maximum working pressure rating
• Steel construction with zinc chromate finish for corrosion resistance
• Hose barb thread type for secure, tool-minimal hose attachment
• Compact overall length of 2.19 inches for tight-clearance installations

Compatibility

Designed as an OEM-style replacement or new-installation connector for pneumatic hose assemblies built to Industrial Interchange standards using 3/8 inch ID hose operating at pressures up to 300 psi.

Installation Notes

Installation should be performed by a qualified technician after fully depressurizing and locking out the pneumatic system. Ensure the hose ID matches the 3/8 inch barb diameter before assembly and secure with an appropriate hose clamp rated for the working pressure. Inspect the zinc chromate finish for damage before installation in corrosive or wet environments. Follow applicable facility safety procedures and OSHA compressed air guidelines during service.
