Parker 231-6-2 Barbed Tube Male Run Tee 3/8 in 1/8-27

Product Description

The PARKER 231-6-2 is a barbed tube male run tee fitting designed for inline fluid or pneumatic line splits where a male threaded branch port is required. Constructed from brass, this fitting connects 3/8 inch OD flexible tubing on the run ends while providing a 1/8-27 male threaded branch outlet. It is well suited for low-pressure plumbing, pneumatic control lines, and light refrigeration or HVAC pilot lines. Plumbers, HVAC technicians, and fluid-handling specialists install this type of fitting when routing tubing through a tee configuration that also needs a threaded connection point. The brass construction offers corrosion resistance and reliable sealing in typical service environments.

This fitting is used in residential and light commercial applications where 3/8 inch OD flexible tubing intersects with a 1/8-27 threaded port. Common install scenarios include pneumatic controls, compressed air distribution, fuel-gas pilot tubing, and water supply manifolds. The barbed run ends grip soft or semi-rigid tubing securely, while the male thread interfaces with standard NPT-compatible fittings, valves, or instrumentation ports. It is a direct inline configuration, meaning flow continues through the run while branching to the threaded port.

Key Features

• Brass construction for corrosion resistance and durability in fluid and pneumatic service
• Barbed run ends accept 3/8 inch OD flexible tubing without additional tools
• 1/8-27 male thread branch port compatible with standard NPT-style connections
• Compact, lightweight design at 0.04 pounds for tight installation spaces
• Inline run-tee configuration allows continuous flow with a side branch outlet

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 3/8 inch OD barbed tubing and 1/8-27 male NPT branch connections in pneumatic, plumbing, or light HVAC control line applications.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified fluid-system technicians. Shut off and depressurize the line before disassembling or installing any fitting. Barbed connections should be secured with appropriate clamps when used in pressurized service. Apply thread sealant to the male NPT branch port in accordance with local plumbing or mechanical codes.
