Parker H12-62-T20 Hydraulic Coupler 1-5/8-12 1000 Psi

Product Description

The PARKER H12-62-T20 is a female straight thread coupler designed for hydraulic hose assemblies operating at pressures up to 1,000 psi. Manufactured from steel with an SAE ORB (O-Ring Boss) shaft type, this fitting provides a leak-resistant, mechanically secure connection in high-demand hydraulic circuits. The 1-5/8-12 thread size and 1.5-inch body diameter make it suited for larger-bore hose terminations where flow capacity and joint integrity are both critical. Hydraulic technicians and industrial maintenance professionals install this coupler as part of hose-end assemblies on mobile and stationary hydraulic equipment.

This coupler is used in hydraulic systems requiring a straight-thread female port connection with an O-ring face seal interface. Typical applications include agricultural machinery, construction equipment, industrial power units, and heavy-duty mobile hydraulics where a straight-thread coupler is specified at pump, valve, or cylinder ports. The SAE ORB thread form minimizes leak paths compared to tapered thread designs, making it a preferred choice in circuits where fluid loss or contamination is a concern.

Key Features

• Female straight thread coupler with SAE ORB interface for reliable, leak-resistant sealing
• Rated to 1,000 psi working pressure for medium-pressure hydraulic circuits
• 1-5/8-12 thread size accommodates larger-bore hydraulic hose ends
• 1.5-inch body diameter for high-flow hydraulic line applications
• Steel construction provides durability in demanding industrial and mobile equipment environments

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose assemblies using SAE ORB straight-thread female coupler connections at the 1-5/8-12 thread size.

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 for damage before assembly and replace if worn; a damaged O-ring is a common source of post-installation leaks. Torque the fitting to the equipment manufacturer's specified value for the port size and thread standard in use.
