Parker 22-6 Barbed Tube Union 0.25 Inch Id Brass

Product Description

The PARKER 22-6 is a brass barbed tube union designed to join two lengths of flexible tubing in a straight-line configuration. It accepts tubing with an inside diameter of 0.25 x 0.25 inches and relies on multiple barbs on each end to grip tubing securely without additional clamps in low-pressure applications. The fitting is constructed from brass, offering corrosion resistance and durability in fluid transfer systems. Plumbers, HVAC technicians, and fluid-systems mechanics install this type of fitting in lines carrying water, air, or compatible fluids where a quick, reliable tube-to-tube connection is needed.

This barbed union is suited for residential and light commercial applications where flexible tubing must be joined mid-run. Common install scenarios include condensate drain lines, low-pressure water supply connections, pneumatic control tubing, and similar fluid transfer lines. Its compact form factor makes it practical in confined spaces where threaded or compression fittings are difficult to seat.

Key Features

• Multiple-barb design on each end holds tubing securely under normal operating conditions
• Brass construction resists corrosion in water and air service
• Accepts 0.25 inch inside diameter tubing on both ends for a straight union connection
• Single-piece body with no moving parts or seals to replace
• Compact profile fits in tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-install barbed tube union for flexible tubing with a 0.25 inch inside diameter in low-pressure fluid transfer applications.

Installation Notes

Installation is performed by plumbers or HVAC technicians as part of tubing assembly or repair work. Shut off fluid or air supply and relieve line pressure before disconnecting or installing any fitting. Push tubing firmly over each barbed end until it seats past all barbs; hose clamps may be added where system pressure or vibration requires a more secure hold. Follow applicable IPC or IFGC guidelines for the specific fluid service and verify tubing material compatibility before installation.
