Parker 12 Flo-s Tube Connector 3/4-14 Orfs X Nptf

Product Description

The PARKER 12 FLO-S is a compression tube connector designed to join hydraulic or fluid lines using an O-Ring Face Seal (ORFS) connection on one end and a National Pipe Taper Fuel (NPTF) thread on the other. Constructed from zinc-plated steel, this fitting provides corrosion resistance suited to industrial and fluid power applications. It accommodates a tube outside diameter of 3/4 inches and carries a maximum working pressure of 5,500 psi, making it appropriate for moderate- to high-pressure hydraulic systems. Plumbers, pipefitters, and hydraulic system technicians install this type of connector during new builds and maintenance service on fluid power equipment.

This connector is used in hydraulic fluid lines, fuel systems, and industrial plumbing installations where a reliable transition between ORFS tubing and NPTF threaded ports is required. The 3/4-14 thread size is a standard sizing found in industrial equipment, mobile hydraulics, and stationary fluid power systems. It is suited for both OEM assembly and field repair work in commercial and industrial environments.

Key Features

• ORFS x NPTF end connections for leak-resistant tube-to-port transitions
• Maximum working pressure of 5,500 psi for high-pressure fluid power service
• Zinc-plated steel construction for corrosion resistance
• 3/4-14 NPTF thread size for compatibility with standard industrial ports
• 3/4 inch tube outside diameter fitment

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems requiring a 3/4-14 NPTF threaded port connection with a 3/4 inch OD ORFS tube interface.

Installation Notes

Installation should be performed by a qualified pipefitter or hydraulic technician. Depressurize and isolate the hydraulic or fluid system completely before removing or installing any fittings. ORFS connections rely on a flat face seal with an O-ring — inspect the O-ring and seating surface for damage before assembly. NPTF threads are self-sealing by design, but confirm thread engagement and system pressure rating before returning the system to service.
