Parker 26-4-2 Barbed Tube Female Connector 1/8-27

Product Description

The PARKER 26-4-2 is a barbed tube female connector designed for secure, leak-resistant tubing connections in fluid and pneumatic systems. Built from brass, this fitting accepts tubing with an inside diameter of 0.17 inches and an outside diameter of 0.25 inches. The female threaded end uses a 1/8-27 thread size, making it compatible with standard NPT-style ports. The multiple-barb design grips the tubing along more than one retention point, reducing the chance of pull-out under pressure or vibration. Plumbers, HVAC technicians, and fluid-system installers use this type of fitting in low-pressure lines where a fast, reliable tube-to-port connection is needed.

This fitting is suited for residential and light commercial applications involving tubing runs to instrumentation ports, control valves, condensate lines, and similar low-pressure fluid or air circuits. The brass construction handles moderate temperature ranges and resists corrosion in typical water, air, and compatible fluid service. It is sold individually and is intended as a direct replacement or new-installation component wherever a 1/8-27 female threaded port and barbed tubing connection are required.

Key Features

• Multiple-barb design provides increased tubing retention and pull-out resistance
• Brass construction offers corrosion resistance for water, air, and compatible fluid service
• 1/8-27 female thread fits standard NPT-style ports
• Accepts tubing with 0.17-inch inside diameter and 0.25-inch outside diameter
• Compact, lightweight fitting at 0.02 pounds for easy handling in tight installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems requiring a 1/8-27 female threaded barbed connector with 0.25-inch OD tubing.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or fluid-system mechanics. Shut off all fluid or air pressure to the line before removing or installing any fitting. Ensure tubing is cut cleanly and pushed fully onto the barb past the retention ribs for a secure connection. Refer to applicable system pressure ratings and use only tubing compatible with the fluid media and operating conditions of the system.
