Parker H0E Pneumatic Hose Coupling 1/4-18 Mnpt

Product Description

The PARKER H0E is a pneumatic hose coupling connector designed for use in compressed air and pneumatic fluid power systems. It features a 3/8 inch body diameter, a 1/4-18 MNPT threaded connection, and a zinc chromate finish over a steel body. Rated to 300 psi maximum working pressure, this connector is built to handle the demands of industrial pneumatic lines. It measures 1.88 inches in overall length and weighs approximately 0.08 pounds. Licensed HVAC techs, pipefitters, and industrial maintenance professionals routinely install this type of hardware in pneumatic control and tool circuits.

This coupling is suited for industrial interchange applications in both light manufacturing and heavy industrial environments. The 1/4-18 NPT thread standard is widely used across pneumatic tool lines, compressor outlets, and control system plumbing. It is sold as a single-piece connector and installs wherever a threaded male NPT pneumatic coupler is required to join hose or tubing to a port or fitting body.

Key Features

• Steel construction with zinc chromate finish for corrosion resistance in industrial environments
• 300 psi maximum working pressure rating for standard pneumatic service
• 1/4-18 MNPT thread for compatibility with standard NPT pneumatic ports
• 3/8 inch body diameter with 0.62 inch hex for wrench installation
• Industrial interchange coupling type for broad pneumatic system use
• Compact 1.88 inch overall length for use in space-constrained installations

Compatibility

Designed as an OEM-style replacement or direct-fit connector for industrial pneumatic systems using 1/4-18 NPT threaded ports and industrial interchange coupling standards.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Always depressurize and bleed down the pneumatic system before removing or installing any coupling. Apply thread sealant appropriate for pneumatic service to the MNPT threads before installation. Torque using an appropriately sized wrench on the hex flats — do not over-tighten, as this can damage the thread engagement or the port.
