Parker 6-6 X6EF-S Steel Swivel Elbow Connector 3/8 in

Product Description

The PARKER 6-6 X6EF-S is a 90-degree swivel elbow connector for flared hydraulic and fluid system tubing. It features a 37-degree flare end on the tube side and a male NPTF thread on the port side, giving technicians a leak-resistant, rotatable connection that simplifies routing in tight spaces. Machined from steel and rated to 6000 psi maximum working pressure, this fitting handles demanding pressure and temperature conditions up to 500 degrees F. It is designed for 3/8-inch OD tube with a 3/8-inch NPTF male thread and conforms to ISO 8434-2 and SAE J514 standards.

This connector is used in hydraulic lines, refrigeration, pneumatic, and fuel system plumbing where a 90-degree directional change is needed without bending or kinking tubing. It is well suited for both shop fabrication and field repair work on mobile equipment, industrial machinery, and commercial HVAC or refrigeration circuits. The swivel feature allows final torquing of the tube nut without twisting the tubing assembly. Licensed HVAC technicians, hydraulic system mechanics, and plumbers working on high-pressure fluid lines are the typical installers.

Key Features

• 90-degree swivel elbow configuration for directional routing flexibility
• 37-degree flare seat conforms to SAE J514 and ISO 8434-2
• Steel construction rated to 6000 psi maximum dynamic working pressure
• Rated for temperatures up to 500 degrees F (260 degrees C)
• Flare x MNPTF end connections for broad system compatibility
• Swivel design prevents tube twist during final tightening

Compatibility

Designed as an OEM-style replacement or direct-fit connector for hydraulic, pneumatic, refrigeration, and fuel plumbing systems using 3/8-inch OD flared tubing with a 3/8-inch NPTF male port connection.

Installation Notes

Installation should be performed by a qualified technician familiar with flared tube fittings and high-pressure fluid systems. Always depressurize and isolate the system before removing or installing any fitting. Verify that the mating tube flare is properly formed to the 37-degree angle before assembly. Follow applicable SAE J514 torque guidelines and consult NEC or IFGC codes as appropriate for the system type.
