Parker H3-62-T8 Hydraulic Coupler 3/8 Inch 4000 Psi Sae Orb

Product Description

The PARKER H3-62-T8 is a female straight thread hydraulic coupler designed for high-pressure fluid power systems. Built to SAE ORB (O-Ring Boss) and ISO 7241-1 Series B standards, this steel coupler handles working pressures up to 4000 psi and flow rates up to 6.00 GPM. The straight body profile and threaded connection make it a direct, leak-resistant fitting for rigid and flexible hydraulic line assemblies. It is installed by hydraulic system technicians and maintenance professionals in industrial and mobile equipment environments where reliable, high-pressure fluid transfer is required.

This coupler is suited for a wide range of applications including industrial hydraulic lines, mobile equipment hydraulic circuits, food and chemical processing systems, water and coolant lines, and gas service lines. The 3/8-inch hose size with a 3/4-16 thread configuration makes it a common choice for mid-range hydraulic circuits found in both stationary and mobile platforms. Its compact overall length of 2.75 inches supports installation in tight plumbing configurations.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and bleed the hydraulic system completely before removing or installing any fittings. Inspect the O-ring seating surface for damage before assembly, and ensure the O-ring is properly seated to achieve a leak-free connection. Follow applicable SAE and ISO standards for torque and assembly procedures when making up hydraulic fittings.
