Parker 16 Flo-s Compression Tube Connector Orfs X Nptf

Product Description

The PARKER 16 FLO-S is a compression tube connector designed for high-pressure hydraulic and fluid system applications. It features an O-Ring Face Seal (ORFS) end on one side and a National Pipe Taper Fuel (NPTF) thread on the other, providing a leak-resistant connection between tube and port. Rated to 4500 psi maximum working pressure, it accommodates a 1-inch tube outside diameter and uses an 1-11-1/2 thread specification. Constructed from zinc-plated steel, the fitting offers corrosion resistance suitable for industrial and mobile hydraulic systems. Licensed plumbers, hydraulic system technicians, and pipefitters typically install this type of connector during system assembly or maintenance.

This fitting is used in hydraulic lines, fluid transfer systems, and high-pressure plumbing assemblies where a transition from a tube connection to an NPTF threaded port is required. It suits both industrial and mobile equipment applications, including hydraulic power units, fluid conveyance systems, and equipment requiring reliable ORFS-to-NPTF transitions. The zinc-plated steel construction makes it appropriate for environments where moderate corrosion resistance is needed alongside high-pressure performance.

Key Features

• ORFS x NPTF end connections for leak-resistant tube-to-port transitions
• 4500 psi maximum working pressure rating
• 1-inch tube outside diameter compatibility
• 1-11-1/2 NPTF thread specification
• Zinc-plated steel construction for corrosion resistance
• Compression-style fitting for secure, vibration-resistant connections

Compatibility

Designed as an OEM-style replacement or direct-fit connector for hydraulic and fluid systems requiring a 1-inch OD tube ORFS connection to a 1-11-1/2 NPTF threaded port.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed pipefitter familiar with high-pressure fluid systems. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Ensure mating surfaces are clean and undamaged before assembly, and verify the O-ring is properly seated before torquing. Follow applicable system design standards and equipment manufacturer specifications for final assembly.
