Parker 10577-20-20 Hydraulic Hose Fitting 3000 Psi

Product Description

The PARKER 10577-20-20 is a male rigid hydraulic hose fitting rated for 3,000 psi service, designed for use in high-pressure hydraulic lines across industrial and mobile equipment applications. Built from steel with an SAE O-Ring Straight Thread (ORST) configuration, this Series 77 fitting provides a leak-resistant sealed connection at the thread interface. It accommodates a 1-1/4 inch hose diameter and uses a 1-5/8-12 thread size. Licensed hydraulic system technicians and industrial mechanics install this fitting when assembling or repairing hydraulic circuits that require a reliable, rigid end connection without swivel movement.

This fitting is suited for hydraulic assemblies found in heavy equipment, construction machinery, agricultural equipment, and industrial hydraulic power units. The male rigid design is appropriate where a fixed, non-rotating connection is required between the hose end and a port or manifold. The SAE O-Ring Straight Thread interface minimizes potential leak points compared to tapered thread designs, making it a common choice for demanding pressure applications in both mobile and stationary hydraulic systems.

Key Features

• 3,000 psi pressure rating suitable for high-pressure hydraulic circuits
• SAE O-Ring Straight Thread interface for leak-resistant sealing at the port
• Male rigid fitting design provides a fixed, non-rotating hose end connection
• Steel construction for durability in demanding hydraulic environments
• Fits 1-1/4 inch hose diameter with a 1-5/8-12 thread size
• Parker Series 77 fitting for consistent dimensional and performance standards

Compatibility

Designed as an OEM-style replacement or new-assembly fitting for hydraulic hose systems requiring a 1-1/4 inch hose end with a 1-5/8-12 SAE O-Ring Straight Thread male rigid connection rated to 3,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit completely before removing or installing any hose fittings. Inspect the O-ring seating surface and replace the O-ring if damaged or missing before assembly. Torque the fitting to the port using hand tools appropriate for the thread size, following applicable industry standards for SAE straight-thread O-ring fittings.
