Parker 2 Etx-s Steel Flared Tube Union 1/8 in 37 Degree

Product Description

The PARKER 2 ETX-S is a steel flared tube union designed to join two flared tube ends in hydraulic, pneumatic, and fluid transfer lines. The fitting uses a 37-degree flare angle on both ends, providing a secure, leak-resistant metal-to-metal seal without the need for additional sealing compounds. Rated to a maximum working pressure of 7500 psi, this union is built for high-pressure service in demanding trade applications. It accepts 1/8 inch tube OD and is sized for compact line installations. Licensed plumbers, HVAC technicians, and industrial pipefitters install this type of fitting in refrigeration, hydraulic, and instrumentation systems.

This union fitting is suited for residential and commercial applications where two tube runs must be joined inline with a reliable flared connection. Typical use cases include refrigeration line repairs, hydraulic circuit assemblies, and instrumentation tubing in process systems. The flare-by-flare end configuration allows direct tube-to-tube connection without adapters. Its compact form factor makes it appropriate for tight spaces where standard compression or threaded fittings are not practical.

Key Features

• 37-degree flare angle on both ends for a metal-to-metal seal
• Maximum working pressure of 7500 psi for high-pressure service
• Accepts 1/8 inch tube OD on each end
• Flare x flare end connection eliminates the need for additional sealing compounds
• Steel construction for durability in hydraulic and fluid transfer applications

Compatibility

Designed as an OEM-style replacement or new-installation union fitting for 1/8 inch OD flared tubing lines in hydraulic, pneumatic, refrigeration, and instrumentation systems using the standard 37-degree flare connection.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or industrial pipefitter. De-pressurize and isolate the line completely before disassembly or fitting installation. Use a calibrated flaring tool to ensure the tube end meets the 37-degree angle specification before tightening; an improper flare is a leading cause of connection failure. Refer to applicable codes such as the IPC or IFGC for tubing material and pressure requirements in your jurisdiction.
