Parker 11C77-25-12 Hydraulic Hose Fitting 12mm 6000 Psi

Product Description

The PARKER 11C77-25-12 is a female metric S 24-degree cone swivel 90-degree elbow fitting designed for high-pressure hydraulic hose assemblies. Built from steel, this Series 77 fitting is rated to 6,000 psi and accepts a 12 mm (3/4 inch) hose end with an M36 x 2.00 metric thread. The 90-degree elbow configuration allows routing hose assemblies in tight spaces or around obstructions where a straight fitting would not clear. Hydraulic system technicians and fluid power specialists install this fitting on mobile equipment, industrial machinery, and other high-pressure hydraulic circuits requiring metric connections.

This fitting is suited for hydraulic systems that use metric S 24-degree cone (DIN 2353 style) swivel connections. The swivel feature allows the hose to be positioned without twisting during assembly, reducing stress on the hose and adjacent components. Typical applications include construction equipment, agricultural machinery, and industrial power units where metric hydraulic plumbing is standard and high-cycle or high-pressure service is expected.

Key Features

• 6,000 psi pressure rating for demanding high-pressure hydraulic service
• Female metric S 24-degree cone seat provides a leak-resistant metal-to-metal seal
• Swivel design prevents hose twist during installation and reduces assembly stress
• 90-degree elbow body allows routing in confined or angled installations
• M36 x 2.00 metric thread size for compatibility with standard metric hydraulic ports
• Steel construction for durability in high-pressure fluid power environments

Compatibility

Designed as a Series 77 OEM-style metric hydraulic hose fitting for use with 12 mm (3/4 inch) hose ends requiring a female metric S 24-degree cone swivel 90-degree elbow connection with M36 x 2.00 thread.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and bleed the hydraulic system completely before removing or installing any fittings. Inspect the cone seat and threads for damage before assembly, and use appropriate hydraulic assembly tools to achieve a proper metal-to-metal seal without over-torquing. Follow equipment manufacturer guidelines and applicable fluid power standards for fitting assembly and system pressure testing.
