Parker 12-16 Flo-s Compression Tube Connector Orfs Nptf

Product Description

The PARKER 12-16 FLO-S is a compression tube connector designed to join hydraulic or fluid-transfer lines using an O-Ring Face Seal (ORFS) connection on one end and a National Pipe Taper Fuel (NPTF) thread on the other. Built from zinc-plated steel, it provides corrosion resistance suitable for demanding fluid system environments. The connector accommodates a 3/4-inch tube outside diameter and is rated for a maximum working pressure of 4500 psi. This fitting is typically installed by hydraulic technicians, plumbers, or industrial maintenance professionals working on high-pressure fluid lines, fuel systems, or similar applications requiring a reliable leak-free seal.

This connector suits applications where a high-pressure hydraulic or fluid line must transition from a tube end to an NPTF threaded port. The ORFS end provides a positive metal-to-metal seal backed by an O-ring, minimizing the risk of leakage under pressure fluctuations. The NPTF thread end creates a pressure-tight connection without relying solely on sealant tape. Common install scenarios include mobile hydraulic equipment, industrial machinery fluid circuits, and fuel delivery systems where a secure tube-to-port transition is required.

Key Features

• ORFS x NPTF end connections for reliable tube-to-port transitions in high-pressure systems
• Rated to 4500 psi maximum working pressure for demanding hydraulic and fluid applications
• Zinc-plated steel construction offers corrosion resistance in harsh service environments
• Fits 3/4-inch outside diameter tubing for consistent, repeatable connections
• NPTF thread standard creates a pressure-tight mechanical seal at the threaded port end

Compatibility

Designed as an OEM-style replacement or direct-fit connector for high-pressure hydraulic and fluid-transfer systems requiring a 3/4-inch OD tube with an ORFS-to-NPTF fitting configuration.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed tradesperson. De-pressurize and isolate the fluid system completely before removing or installing any fittings. Inspect the O-ring seating surface for nicks or contamination before assembly, as surface damage on the ORFS face can cause leaks under pressure. Follow applicable industry standards and equipment manufacturer torque guidelines when tightening threaded connections.
