Parker 6 Flo-s Tube Connector Orfs Nptf 1/4-18 6000 Psi

Product Description

The PARKER 6 FLO-S is a compression tube connector designed for high-pressure hydraulic and fluid system applications. It features an O-Ring Face Seal (ORFS) inlet and a National Pipe Taper Fuel (NPTF) outlet, providing a leak-resistant connection rated to 6000 psi maximum working pressure. Constructed from zinc-plated steel, it delivers corrosion resistance suited to industrial and mobile equipment environments. This fitting bridges ORFS tube connections to NPTF-threaded ports and is sized at 1/4-18 thread. Licensed plumbers, hydraulic technicians, and fluid power specialists are the typical installers of this fitting in production and field service work.

This connector is used wherever an ORFS tube end must transition to an NPTF threaded port, including hydraulic power units, mobile machinery, industrial fluid lines, and equipment requiring a dry-seal thread connection on one end and a face-seal tube connection on the other. Its 6000 psi pressure rating makes it appropriate for high-pressure hydraulic circuits in both stationary and mobile applications. It is sold and packaged individually, with a minimum order quantity of one unit.

Key Features

• ORFS x NPTF end connections allow transition between O-ring face seal tube fittings and dry-seal pipe threads
• Maximum working pressure of 6000 psi suits high-pressure hydraulic systems
• Zinc-plated steel construction provides corrosion resistance in industrial environments
• 1/4-18 NPTF thread size conforms to National Pipe Taper Fuel thread standards for dry-seal performance
• Compact connector form factor for space-constrained hydraulic plumbing runs

Compatibility

Designed as an OEM-style replacement or new-install fitting for hydraulic and fluid power systems requiring an O-Ring Face Seal to NPTF transition at 1/4-18 thread size and up to 6000 psi working pressure.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed fluid power specialist. Depressurize and bleed down the hydraulic circuit fully before removing or installing any fittings. Inspect the O-ring sealing face and the NPTF threads for damage before assembly; do not reuse deformed or nicked O-rings. Tighten to the fitting manufacturer's recommended torque range for the thread size using calibrated torque tooling, and verify zero leakage under pressure before returning the system to service.
