Parker 14-3/4 F5OF-S Hex Plug 1-3/16-12 X 3/4 Sae-orb Nptf

Product Description

The PARKER 14-3/4 F5OF-S is a straight hex plug fitting designed for industrial hydraulic and fluid power applications. It connects a male SAE-ORB (O-Ring Boss) thread to a male NPTF (National Pipe Tapered Fuel) thread, allowing technicians to terminate or redirect fluid circuits where both port types intersect. The fitting is rated for a maximum working pressure of 4,500 psi with a pressure rating of 5,000 psi, making it suitable for high-pressure hydraulic lines. A 1-3/8 inch hex size allows for standard wrench engagement during installation. It is typically installed by hydraulic technicians, millwrights, or industrial mechanics servicing fluid power systems.

This hex plug is used in industrial fluid power assemblies where a SAE-ORB port must be capped or transitioned to an NPTF connection. Common install scenarios include hydraulic manifolds, cylinder ports, pump outlets, and valve bodies in both mobile and stationary industrial equipment. The straight fitting shape keeps the assembly compact and in-line with existing port geometry.

Key Features

• Maximum working pressure of 4,500 psi
• Pressure rating of 5,000 psi for high-demand hydraulic circuits
• 1-3/8 inch hex size for secure wrench engagement
• Compact straight fitting shape for in-line port applications
• Thread size 1-3/16-12 x 3/4 inch for precise thread engagement

Compatibility

Designed as an OEM-style replacement hex plug fitting for industrial hydraulic and fluid power systems requiring a male SAE-ORB to male NPTF straight connection at the specified thread sizes.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic. Depressurize and isolate the hydraulic circuit fully before removing or installing any fitting. Inspect both mating threads and the O-ring seating surface for damage before assembly. Do not overtighten NPTF connections; follow applicable fluid power standards for thread engagement and torque guidance.
