Parker 16 F6L-S Swivel Connector 1 in Od Orfs X Nptf

Product Description

The PARKER 16 F6L-S is a compression tube pipe thread swivel connector designed for high-pressure hydraulic and fluid system plumbing. It joins a 1-inch outside diameter compression tube to a 1-11/2 inch NPTF pipe thread using an O-Ring Face Seal (ORFS) interface on the tube side. Constructed from steel, this fitting handles working pressures up to 4500 psi, making it suitable for demanding industrial and mobile hydraulic circuits. Licensed plumbers, pipefitters, and hydraulic system technicians install this type of fitting where a leak-free, rotatable connection between rigid tubing and threaded ports is required.

This swivel connector is used in hydraulic plumbing, fluid power systems, and industrial piping applications where tube-to-pipe-thread transitions are needed. The ORFS seat provides a metal-to-metal sealing surface backed by an O-ring, reducing leak paths under pressure cycling or vibration. The swivel feature allows the fitting to rotate during assembly, which simplifies installation in tight or congested equipment layouts. Typical applications include hydraulic power units, mobile equipment, and industrial machinery where tube lines must terminate at NPTF-ported components.

Key Features

• Steel construction for durability in high-pressure service up to 4500 psi
• ORFS tube end provides O-ring-backed face seal for leak-resistant performance under pressure cycling
• NPTF pipe thread end conforms to dryseal thread standard, reducing reliance on thread sealant
• Swivel body allows rotation during assembly to ease installation in confined spaces
• 1-inch tube OD and 1-11/2 inch NPTF thread sizes suit common hydraulic line configurations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems requiring a 1-inch OD compression tube to 1-11/2 inch NPTF swivel connection with an ORFS sealing interface.

Installation Notes

Installation should be performed by a qualified pipefitter, hydraulic technician, or licensed plumber. Depressurize and bleed down the hydraulic circuit fully before removing or installing any fitting. Inspect the O-ring and ORFS sealing face for nicks or contamination before assembly, and replace the O-ring if damaged. Torque the fitting per the system designer or equipment manufacturer specifications; do not over-torque steel compression fittings.
