Parker 1719846 Female O-ring Boss Coupler 4000 Psi

Product Description

The PARKER 1719846 is a female O-ring boss (ORB) hydraulic hose coupler designed for high-pressure hydraulic systems. Rated at 4,000 psi, it provides a leak-resistant metal-to-metal seal backed by an O-ring at the boss port. Constructed from steel with a 7/8-14 thread size and a body diameter of 0.5 inches, this fitting meets SAE standards for hydraulic circuit connections. Licensed hydraulic technicians and industrial maintenance mechanics install this type of coupler in mobile and stationary hydraulic applications where reliable sealing under sustained pressure is required.

This coupler is suited for residential, commercial, and industrial hydraulic systems where a female ORB port connection is needed. It is commonly used in hydraulic hose assemblies, manifold connections, and equipment circuits that operate with petroleum-based or compatible hydraulic fluids. The SAE thread form and steel construction make it a standard choice for agricultural, construction, and material-handling equipment hydraulic lines.

Key Features

• 4,000 psi pressure rating for high-pressure hydraulic circuits
• Female O-ring boss (ORB) thread form provides a positive, leak-resistant seal
• 7/8-14 thread size conforms to SAE specifications
• Steel construction for strength and durability in demanding environments
• 0.5 inch body diameter for compact installation in tight spaces

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose assemblies requiring a female O-ring boss coupler with a 7/8-14 SAE thread and 4,000 psi pressure rating.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic familiar with hydraulic circuit safety. Depressurize and lock out the hydraulic system completely before disconnecting or installing any fittings. Inspect the O-ring for damage before assembly and ensure the mating boss port surface is clean and free of burrs. Follow applicable SAE and equipment manufacturer torque guidelines for ORB fittings when tightening.
