Parker 1720576 Female O-ring Boss Nipple 4000 Psi

Product Description

The PARKER 1720576 is a female O-ring boss nipple fitting designed for hydraulic hose assemblies operating at pressures up to 4,000 psi. Constructed from steel, this fitting features a 7/8-14 thread size and a 1/2-inch body diameter, conforming to SAE standards. It provides a leak-resistant seal through metal-to-metal contact combined with an O-ring at the boss port. Licensed hydraulic technicians and industrial maintenance professionals install this fitting in high-pressure hydraulic lines across mobile and stationary equipment applications.

This fitting is suited for hydraulic systems requiring a reliable, reusable female boss connection at the hose end. It is commonly installed in agricultural, construction, and industrial machinery where SAE O-ring boss port connections are specified. The steel construction handles demanding duty cycles and exposure to hydraulic fluid without deformation at rated pressure.

Key Features

• Rated to 4,000 psi working pressure for demanding hydraulic circuits
• 7/8-14 thread size conforms to SAE O-ring boss standards
• Steel body construction resists deformation under pressure and mechanical stress
• 1/2-inch body diameter for compatibility with standard hydraulic hose ends
• O-ring boss design provides positive, leak-resistant sealing at the port face

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic hose assemblies requiring a female O-ring boss nipple with 7/8-14 SAE thread.

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 for damage before assembly and ensure the mating boss port face is clean and free of nicks. Torque to the hose or port manufacturer specifications using appropriate hydraulic assembly tooling.
