Parker 12-8 Flo-s Compression Tube Connector Orfs X Nptf

Product Description

The PARKER 12-8 FLO-S is a compression tube connector designed for high-pressure hydraulic and fluid system applications. It features an O-Ring Face Seal (ORFS) to National Pipe Thread Fuel (NPTF) end connection configuration, providing a leak-free seal in demanding service environments. The connector accommodates a 3/4 inch tube outside diameter and carries a maximum working pressure rating of 6000 psi. Constructed from zinc-plated steel, it delivers corrosion resistance appropriate for industrial and mobile fluid power installations. Licensed plumbers, pipefitters, and hydraulic system technicians are the primary installers of this fitting type.

This connector is suited for hydraulic lines, fluid power circuits, and high-pressure tubing assemblies where a transition from ORFS tubing to an NPTF port is required. It is appropriate for both stationary industrial equipment and mobile machinery applications. The 1/2-14 NPTF thread size is a common port size found across a wide range of hydraulic manifolds, cylinders, valves, and pumps, making this fitting a frequently specified component in fluid system assembly and repair work.

Key Features

• ORFS x NPTF end connections provide a reliable, leak-resistant interface between tube and threaded port
• Maximum working pressure of 6000 psi supports high-pressure hydraulic service
• 3/4 inch tube outside diameter compatibility for standard hydraulic tubing
• Zinc-plated steel construction provides corrosion resistance in industrial environments
• 1/2-14 NPTF thread standard ensures a pressure-tight mechanical seal without sealant tape on the port side
• Overall length of 1.93 inches suits compact plumbing configurations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems requiring a 3/4 inch OD ORFS tube connection to a 1/2-14 NPTF threaded port.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with high-pressure fluid system assembly. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. The ORFS connection relies on a properly seated O-ring against a flat face port for its seal — inspect the O-ring and sealing face for damage before assembly. Follow the equipment manufacturer and applicable industry torque guidelines for ORFS fittings; do not overtighten.
