Value Collection 16217 Steel Flared Tube Union 3/8 in

Product Description

The VALUE COLLECTION 16217 is a steel flared tube union designed to join three flared tubing lines at a single junction point. Built with a 37-degree flare seat and a 9/16-18 thread on all three ports, this union accepts 3/8-inch OD tubing on each connection. It is a standard fitting used in hydraulic, pneumatic, and fluid-transfer line assemblies where a three-way union junction is required. Licensed plumbers, HVAC technicians, and industrial pipe fitters install this type of fitting when routing or branching flared metal tubing in equipment or system plumbing.

This union is suited for applications requiring a three-port flared connection in steel tubing assemblies. The 37-degree flare angle conforms to SAE flare standards commonly used in refrigeration line sets, hydraulic circuits, and compressed-air or fuel-line plumbing in commercial and light industrial settings. All three ports share the same 9/16-18 thread size, making this a symmetric fitting appropriate for in-line or branch configurations with 3/8-inch OD tubing.

Key Features

• 37-degree flare angle on all three ports matches SAE-standard flared tubing
• 9/16-18 thread size on each connection for consistent torque and sealing
• Accepts 3/8-inch OD tubing at every port
• Steel construction provides strength for pressurized line service
• Symmetric three-port design supports union or branch configurations

Compatibility

Designed as a standard SAE 37-degree flare union fitting for use with 3/8-inch OD steel tubing and 9/16-18 threaded flare nuts in hydraulic, pneumatic, refrigeration, and fuel-line assemblies.

Installation Notes

Installation should be performed by a qualified technician familiar with flared tube fitting assembly. Depressurize and isolate the line before disassembly or installation. Use a calibrated flaring tool to produce a consistent 37-degree flare seat on all tubing ends before tightening the flare nuts. Do not overtighten flare connections; follow the applicable system code or equipment manufacturer guidance for final torque.
