Parker H2-62-T6 Hydraulic Hose Coupler 5000 Psi 9/16-18

Product Description

The PARKER H2-62-T6 is a female straight thread hydraulic hose coupler rated for 5,000 psi working pressure. Machined from steel, it features a 9/16-18 thread size and an SAE ORB (O-Ring Boss) sealing interface, which provides a leak-resistant metal-to-metal seat backed by an elastomeric o-ring. This coupler connects hydraulic hose assemblies to ports in hydraulic circuits found on mobile equipment, industrial machinery, and fluid power systems. It is installed by hydraulic system technicians and equipment mechanics during hose assembly fabrication or field repair.

This coupler is suited for high-pressure hydraulic circuits operating up to 5,000 psi. The SAE ORB port style is common in mobile hydraulic applications including construction equipment, agricultural machinery, and industrial presses. With a 1/4-inch body diameter, this fitting is designed for compact hose routing in tight plumbing configurations. It is appropriate for use with hydraulic fluids in systems requiring reliable, reusable threaded connections at hose termination points.

Key Features

• 5,000 psi pressure rating for demanding high-pressure hydraulic circuits
• SAE ORB sealing interface minimizes leak paths compared to tapered thread designs
• Steel construction for durability in industrial and mobile equipment environments
• 9/16-18 female straight thread for positive engagement with SAE ORB port fittings
• 1/4-inch body diameter suited for compact hose assemblies

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose assemblies using SAE ORB straight thread port connections at 9/16-18 thread size and 1/4-inch body diameter.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the o-ring seat and o-ring for damage before assembly, and replace the o-ring if worn or cut to prevent leaks. Torque to the fitting manufacturer and system designer specifications for SAE ORB connections; do not overtighten, as this can damage the o-ring or seat.
