Parker FEM-751-12FO Hydraulic Hose Coupler 3/4 in Sae Orb

Product Description

The PARKER FEM-751-12FO is a valved, no-lock female straight-thread hydraulic hose coupler designed for high-pressure hydraulic systems. It features a 3/4 inch SAE ORB (O-Ring Boss) fitting with a 1-1/16-12 thread size and is rated for a maximum working pressure of 5,000 psi. The coupler measures 3.95 inches in overall length and handles flow rates up to 26.00 GPM. Constructed from zinc-nickel plated steel, it delivers corrosion resistance in demanding field environments. This coupler is installed by hydraulic equipment technicians and heavy equipment service professionals working on fluid-power circuits.

The FEM-751-12FO is suited for use with hydraulic tools and skid loader attachments in both mobile and stationary hydraulic systems. Its inline, straight configuration makes it a direct-fit choice for standard hydraulic hose assemblies where a female SAE ORB threaded connection is required. The general-purpose housing and valved design make it appropriate for residential and commercial equipment service applications where fluid containment during disconnect is a priority.

Key Features

• Valved design contains hydraulic fluid during connect and disconnect operations
• Zinc-nickel plated steel construction for corrosion resistance in harsh environments
• Rated to 5,000 psi maximum working pressure
• Supports up to 26.00 GPM maximum flow rate
• 3/4 inch SAE ORB female fitting with 1-1/16-12 thread for secure, leak-resistant sealing
• Inline straight configuration simplifies hose routing and assembly
• Meets ISO 16028 standards for flat-face hydraulic couplings

Compatibility

Designed for use with hydraulic tools and skid loader attachments requiring a 3/4 inch female SAE ORB straight-thread coupler in hydraulic hose assemblies rated to 5,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Always depressurize and relieve residual hydraulic pressure from the system before disconnecting or installing any coupler. Inspect the O-ring sealing surface for nicks or debris before threading the coupler into the port. Torque to the fitting manufacturer specifications for the thread size and confirm there are no leaks under system pressure before returning equipment to service.
