Parker 1J977-16-12 Hydraulic Hose Fitting 90 Elbow 3/4 in

Product Description

The PARKER 1J977-16-12 is a female Seal-Lok swivel short drop 90-degree elbow fitting designed for hydraulic hose assemblies in high-pressure fluid power systems. Rated to 6,000 psi, this Series 77 fitting connects 3/4-inch hydraulic hose to a 1-7/16-12 SAE O-Ring Straight Thread port. The steel construction and swivel design allow rotational positioning during assembly, reducing hose stress at the connection point. It is installed by hydraulic system technicians and fluid power specialists on mobile equipment, industrial machinery, and agricultural systems.

This fitting is suited for use in hydraulic lines requiring a compact 90-degree elbow at the hose-to-port interface. The short drop geometry keeps the fitting profile low where space is limited. The SAE O-Ring Straight Thread (ORST) sealing interface provides a leak-resistant metal-to-face seal, making it appropriate for high-cycle and high-pressure applications. Typical install environments include construction equipment, agricultural machinery, industrial presses, and mobile hydraulic systems where hose routing requires a right-angle transition.

Key Features

• 6,000 psi pressure rating suitable for high-pressure hydraulic circuits
• Female Seal-Lok swivel design allows rotational alignment during assembly without twisting the hose
• Short drop 90-degree elbow geometry reduces fitting envelope in tight routing applications
• SAE O-Ring Straight Thread interface for reliable leak-resistant sealing
• Steel construction for durability in demanding hydraulic environments
• Series 77 Parker fitting with 3/4-inch hose end and 1-7/16-12 thread size

Compatibility

Designed as an OEM-style hydraulic hose end fitting compatible with 3/4-inch hydraulic hose assemblies terminating at a 1-7/16-12 SAE O-Ring Straight Thread port. Consult the Parker Series 77 fitting catalog to confirm hose I.D. and system pressure compatibility before installation.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit completely before disconnecting or installing any fitting. Clean the port and fitting threads before assembly and inspect the O-ring for damage prior to torquing. Follow applicable hydraulic system design standards and equipment manufacturer torque specifications when securing the fitting to the port.
