Parker EZ-251-6HB Pneumatic Hose Coupling 1/4 in

Product Description

The PARKER EZ-251-6HB is a steel pneumatic hose coupling designed for use in compressed air and pneumatic fluid systems. Part of the E-Z Mate series, this coupler features a hose barb thread type and an Industrial Interchange design, making it widely compatible with standard pneumatic tooling setups. It accepts a 3/8 inch inside diameter hose and has a 1/4 inch body diameter. Rated for a maximum working pressure of 300 psi and a temperature range of -40 degrees F to 250 degrees F, this coupler is built for demanding shop and field environments. Licensed HVAC techs, pipefitters, and pneumatic system technicians are the typical installers.

This coupling is suited for residential and light commercial pneumatic systems where Industrial Interchange fittings are the standard. The hose barb end connects directly to flexible pneumatic hose with a 3/8 inch inside diameter, eliminating the need for threaded fittings on the hose side. It is commonly used at the termination point between a pneumatic tool drop line and a flexible supply hose. The 3.2 inch overall length and 0.75 inch hex size allow for straightforward installation with standard hand tools in tight service spaces.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize the pneumatic circuit fully before disconnecting or installing any coupling. Secure the hose barb connection with an appropriate clamp rated for the system pressure. Verify that the hose inside diameter and system pressure do not exceed the rated limits of this fitting before placing it into service.
