Parker BD-FF-75112FO-1 Hydraulic Hose Coupler 3000 Psi

Product Description

The PARKER BD-FF-75112FO-1 is a steel hydraulic hose coupler designed for high-pressure fluid power applications. Built to a 3,000 psi maximum working pressure rating, it accepts a 12 mm (3/4 inch) hose diameter and connects via a 1-1/16-12 UNF threaded interface. The coupler measures 3.75 inches in overall length and supports a maximum flow rate of 28.00 GPM. It is suited for use in mobile hydraulic systems, industrial machinery, and equipment requiring reliable, leak-resistant hose-to-component connections. Hydraulic system technicians and fluid power mechanics are the primary installers of this fitting.

This coupler is used in applications where a threaded UNF connection is required at the hose end of a hydraulic circuit. The FF series designation indicates its intended use in high-cycle, high-pressure hydraulic assemblies common in construction, agricultural, and industrial equipment. The 3/4 inch hose diameter and 3,000 psi working pressure make it appropriate for mid- to high-pressure circuits in both mobile and stationary hydraulic systems. It ships individually and can be ordered in single-unit quantities.

Key Features

• 12 mm (3/4 inch) hose diameter compatibility in the Parker FF series
• 1-1/16-12 UNF threaded connection type for secure, leak-resistant assembly
• Steel construction for durability under high-pressure cycling
• Maximum flow rate of 28.00 GPM supports moderate- to high-flow hydraulic circuits
• 3.75 inch overall length fits standard hydraulic hose assembly configurations

Compatibility

Designed as an OEM-style replacement or new-assembly coupler for hydraulic hose systems requiring a 3/4 inch hose diameter, 1-1/16-12 UNF threaded connection, and a 3,000 psi pressure rating within the Parker FF series.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power systems. Depressurize and isolate the hydraulic circuit fully before disconnecting or installing any fitting. Use appropriate thread sealant or hydraulic-rated tape as required by system specifications, and torque connections according to the system manufacturer's guidelines. Inspect hose ends and mating threads for damage or contamination before assembly to prevent leaks or premature fitting failure.
