Parker 4 Ftx-s Steel Flared Tube Connector 1/4 in Od

Product Description

The PARKER 4 FTX-S is a steel flared tube connector designed to join 1/4 inch OD tubing to a male NPTF threaded port using a 37-degree flare seat. It provides a leak-resistant mechanical connection rated for demanding fluid and pneumatic system applications. The fitting uses a Flare x MNPTF end configuration, making it a standard transition piece between flared tubing and NPT-threaded ports. With a maximum working pressure of 6000 psi and a maximum working temperature of 500 degrees F, it is built for high-pressure hydraulic and instrumentation lines. Licensed HVAC technicians, plumbers, and fluid-power mechanics are the typical installers.

This connector is suited for residential and commercial applications wherever 1/4 inch OD steel tubing must terminate at an NPTF-threaded component. Common install scenarios include hydraulic control circuits, refrigeration and HVAC copper or steel line sets, and instrumentation tubing runs that require a reliable 37-degree flare joint conforming to SAE J514 and ISO 8434-2 standards. It is sold as a single piece, making it practical for service calls requiring a single fitting replacement without purchasing a full kit.

Key Features

• 37-degree flare seat conforms to SAE J514 and ISO 8434-2 standards
• Flare x MNPTF end connection for transitioning flared tubing to NPT-threaded ports
• Rated to 6000 psi maximum working pressure
• Maximum working temperature of 500 degrees F (260 degrees C)
• Steel construction for durability in high-pressure hydraulic and fluid systems
• Compact overall length of 1.22 inches for tight installation spaces

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 1/4 inch OD tubing with 37-degree flare connections and NPTF-threaded ports, conforming to SAE J514 and ISO 8434-2 specifications.

Installation Notes

This fitting is typically installed by licensed HVAC technicians, hydraulic mechanics, or plumbers working on pressurized fluid or refrigerant lines. Depressurize and isolate the system completely before removing or installing any flare fitting. Use a calibrated flaring tool to form a proper 37-degree flare on the tubing end before seating the connector to avoid leaks. Follow applicable codes such as the IFGC, IPC, or system manufacturer guidelines for torque and assembly procedures.
