Parker 12 Ftx-s Steel Flared Tube Connector 3/4 in

Product Description

The PARKER 12 FTX-S is a steel flared tube connector designed for high-pressure hydraulic and fluid power applications. It features a 37-degree flare profile on one end and a male NPTF thread on the other, creating a reliable, leak-resistant connection between flared tubing and threaded ports. Built from steel with a maximum working pressure of 5000 psi and a temperature rating of 500 degrees F (260 degrees C), this fitting is suited for demanding industrial and mobile hydraulic systems. Licensed HVAC technicians, hydraulic system installers, and fluid power mechanics install this type of connector in service and fabrication work.

This connector is used in hydraulic lines, pneumatic circuits, and fluid transfer systems where a 3/4 inch OD tube must terminate at a threaded port. The 37-degree flare conforms to SAE J514 and ISO 8434-2 standards, making it a recognized fitting style across OEM and aftermarket hydraulic plumbing. Typical applications include construction equipment, industrial machinery, and other systems requiring a durable steel fitting rated for high-cycle pressure service.

Key Features

• 37-degree flare seat conforms to SAE J514 and ISO 8434-2 standards
• Flare x MNPTF end connections for tubing-to-port transitions
• Rated to 5000 psi maximum working pressure
• Operates from ambient temperatures up to 500 degrees F (260 degrees C)
• Steel construction for durability in industrial and mobile hydraulic environments
• Overall length of 2.06 inches suits standard inline plumbing configurations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems using 3/4 inch OD flared tubing with NPTF-threaded ports, per SAE J514 and ISO 8434-2 specifications.

Installation Notes

Installation is performed by qualified hydraulic technicians or licensed plumbers. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. The NPTF thread is a dry-seal design intended to seal on the threads themselves; apply thread sealant only if required by the system designer and per applicable specifications. Torque the fitting per the system OEM or SAE J514 assembly guidelines using calibrated tooling — do not use field-estimated torque.
