Parker EZ-501-8FP Pneumatic Hose Coupler 1/2 Inch Steel

Product Description

The PARKER EZ-501-8FP is a steel pneumatic hose coupler from the E-Z Mate series, designed for industrial interchange pneumatic systems. With a 1/2 inch body diameter and a 1/2-14 female NPTF threaded connection, it handles working pressures up to 300 psi and operates across a temperature range of -40 degrees F to 250 degrees F. At 3.01 inches in overall length and 0.65 pounds, this coupler is a compact, durable fitting suited for connecting compressed air lines in plant, shop, and field environments. Installation and service are handled by licensed pipefitters, HVAC technicians, or qualified maintenance professionals.

The EZ-501-8FP is used in industrial compressed air distribution systems where Industrial Interchange-style couplings are the facility standard. It threads into female NPTF ports on hoses, manifolds, regulators, and inline tools. The 1/2-14 thread size fits common mid-flow compressed air connections found throughout manufacturing, maintenance, and mechanical service operations. Its steel construction makes it appropriate for demanding shop environments where durability under repeated connect-disconnect cycles is required.

Key Features

• Industrial Interchange coupling type for broad compatibility with standard pneumatic quick-connect systems
• Female NPTF 1/2-14 threaded connection provides a pressure-tight, tapered thread seal
• 300 psi maximum working pressure rated for typical compressed air service
• Wide operating temperature range of -40 degrees F to 250 degrees F
• Steel construction for durability in high-cycle shop and industrial environments
• Compact at 3.01 inches overall length with 1.12 inch hex size for standard wrench installation

Compatibility

Designed as an OEM-style Industrial Interchange coupler compatible with standard 1/2 inch pneumatic quick-connect systems using Female NPTF 1/2-14 threaded ports in compressed air service.

Installation Notes

Installation is performed by qualified pipefitters or mechanical technicians. Depressurize and lockout the compressed air system completely before replacing or installing any coupler. Apply thread sealant appropriate for pneumatic service to the NPTF threads and tighten to fitting using a wrench on the 1.12 inch hex — do not over-tighten. Verify the system is leak-free at operating pressure before returning to service.
