Parker 6-8 Flo-s Compression Tube Connector Orfs X Nptf

Product Description

The PARKER 6-8 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 Thread Fuel (NPTF) connection on the other. Built from zinc-plated steel, it provides corrosion resistance in demanding fluid system environments. The connector accepts 3/8-inch outside diameter tubing and features a 1/2-14 NPTF thread. It is rated for a maximum working pressure of 6000 psi, making it suitable for high-pressure hydraulic and fluid power applications. Licensed plumbers, hydraulic technicians, and fluid power specialists install this fitting in industrial and mobile equipment systems.

This connector is used in hydraulic plumbing, fluid power circuits, and industrial piping systems where a transition between ORFS tubing and NPTF threaded ports is required. It is applicable in both stationary and mobile equipment installations, including construction, agricultural, and manufacturing machinery. The compact connector format suits tight routing situations where a straight inline transition is needed between tube and threaded port.

Key Features

• ORFS x NPTF end connections allow transition from tube to threaded port in a single fitting
• Rated to 6000 psi maximum working pressure for high-pressure hydraulic service
• Accepts 3/8-inch outside diameter tubing
• 1/2-14 NPTF thread standard for leak-free threaded connections
• Zinc-plated steel construction provides corrosion resistance
• Sold as individual unit, no minimum order requirement beyond single piece

Compatibility

Designed as an OEM-style replacement or direct-install compression tube connector for hydraulic and fluid power systems requiring a 3/8-inch OD tube to 1/2-14 NPTF port connection with an O-Ring Face Seal interface.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with high-pressure fluid systems. Depressurize and bleed the system fully before removing or installing any fittings. Inspect the O-ring sealing face for nicks or contamination prior to assembly, as surface damage will compromise the seal. Follow applicable fluid power system codes and equipment manufacturer guidelines for torque and assembly procedures.
