Parker H5EP Pneumatic Hose Coupling 3/8 in Industrial

Product Description

The PARKER H5EP is a steel pneumatic hose coupling designed for industrial compressed-air and pneumatic fluid-power systems. It functions as a connector using a Push-Lok hose barb thread type, accepting 3/8-inch inside diameter hose and featuring a 3/8-inch body diameter. Rated to a maximum working pressure of 300 psi, the H5EP is built for demanding shop and field environments where reliable, leak-free connections are required. A zinc chromate finish provides corrosion resistance. Licensed HVAC technicians, pipefitters, and industrial maintenance professionals install this type of fitting as part of pneumatic tool lines, compressor distribution networks, and fluid-power circuits.

The H5EP is suited for industrial interchange applications in both light and heavy commercial environments. It is typically installed on pneumatic hose assemblies where a secure barb-style connector is needed at the hose end. The industrial interchange coupling style is widely used in manufacturing, maintenance, and mechanical contracting settings where standardized fittings are required for tool and equipment compatibility.

Key Features

• 3/8-inch body diameter with 3/8-inch hose inside diameter for direct hose barb attachment
• Maximum working pressure of 300 psi for reliable performance in industrial pneumatic systems
• Push-Lok hose barb thread type for secure, tool-assisted hose installation
• Steel construction with zinc chromate finish for corrosion resistance
• Industrial interchange coupling type for broad compatibility across standard pneumatic systems
• Overall length of 2.17 inches with 0.86-inch hex size for wrench engagement

Compatibility

Designed as an OEM-style industrial interchange connector for pneumatic hose assemblies using 3/8-inch inside diameter Push-Lok hose in compressed-air and fluid-power applications.

Installation Notes

Installation is typically performed by licensed pipefitters, industrial mechanics, or qualified pneumatic system technicians. Depressurize and lock out the air supply before replacing or installing any pneumatic coupling. A properly sized wrench should be used on the hex to avoid rounding; do not overtighten. Verify hose inside diameter matches the fitting barb size before assembly to ensure a secure, leak-free connection.
