Parker 10 Etx-s Steel Flared Tube Union 5/8 in 37 Degree

Product Description

The PARKER 10 ETX-S is a steel flared tube union designed to connect two flared tube ends in hydraulic and fluid power plumbing systems. It features a 37-degree flare angle on both ends and accepts 5/8-inch tube OD, conforming to SAE J514 and ISO 8434-2 standards. Rated to a maximum working pressure of 5000 psi and a maximum working temperature of 500 degrees F (260 degrees C), this union is built for demanding service conditions in industrial and mobile equipment applications. Licensed plumbers, hydraulic technicians, and fluid power specialists install this type of fitting during new construction and service work.

This tube union is suited for use in hydraulic lines, fuel systems, and instrumentation tubing where a leak-free flared connection is required. The flare x flare end configuration makes it appropriate for inline unions joining two tube runs of equal diameter. It is a common component in mobile hydraulic circuits, industrial machinery plumbing, and commercial fluid power systems where steel fittings meeting SAE and ISO specifications are specified.

Key Features

• 37-degree flare angle on both ends meets SAE J514 and ISO 8434-2 specifications
• 5/8-inch tube OD sizing for precise, leak-free connection
• Rated to 5000 psi maximum working pressure
• Temperature range up to 500 degrees F (260 degrees C)
• Steel construction for durability in hydraulic and fluid power applications
• Flare x flare end connection for straightforward inline tube joining

Compatibility

Designed as an OEM-style flared tube union for hydraulic and fluid power systems requiring 5/8-inch tube OD, 37-degree SAE flare fittings per SAE J514 and ISO 8434-2 standards.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with SAE flare fitting procedures. Depressurize and fully isolate the fluid system before removing or installing fittings. Use appropriate tube flaring tools to achieve a proper 37-degree seat before assembly; do not overtighten, as flare fittings rely on metal-to-metal seating rather than thread engagement alone. Verify all connections are leak-free before returning the system to service.
