Parker 1719907 Female Orb Hydraulic Hose Coupler 4000 Psi

Product Description

The PARKER 1719907 is a female O-Ring Boss (ORB) hydraulic hose coupler designed for high-pressure hydraulic line connections in mobile and industrial equipment. Machined from steel with an SAE-standard configuration, this fitting seals through face-to-face O-ring contact, which eliminates the leak paths associated with tapered thread connections. It carries a 4,000 psi pressure rating and is built to the 1-1/16-12 thread specification. Licensed HVAC, industrial, and hydraulic technicians rely on fittings like this to maintain reliable, leak-free connections in demanding fluid power systems.

This coupler suits hydraulic hose assembly and plumbing applications in agricultural machinery, construction equipment, industrial power units, and mobile hydraulic circuits. The female ORB design threads directly into a male ORB port on pumps, valves, cylinders, or manifolds. The 1/2-inch body diameter and 1-1/16-12 thread size position it for mid-range hydraulic lines that operate under sustained system pressure up to 4,000 psi. A single unit is supplied per package.

Key Features

• 4,000 psi pressure rating for high-pressure hydraulic circuits
• Female O-Ring Boss configuration provides a reliable, leak-resistant face seal
• Steel construction for strength and durability in demanding fluid power environments
• SAE-standard thread profile ensures broad compatibility with ORB-ported components
• 1-1/16-12 thread size and 1/2-inch body diameter for mid-range hydraulic hose assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic systems using SAE O-Ring Boss (ORB) ported components with a 1-1/16-12 female thread interface.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with SAE J1926 ORB fitting standards. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect and replace the O-ring if it shows any sign of damage, compression set, or incompatibility with the system fluid before assembly. Verify thread engagement and seating torque per the equipment manufacturer's service documentation.
