Parker PP4TCB4 Tube to Barb Connector 1/4 in Od

Product Description

The PARKER PP4TCB4 is a push-to-connect tube-to-barb connector designed for quick, tool-free tubing connections in fluid handling and pneumatic systems. Constructed from polypropylene, this fitting accepts 1/4 inch OD tubing on the push-to-connect end and terminates to a barbed outlet for secure hose attachment. It is rated to 150 psi, making it suitable for a wide range of low-to-medium pressure plumbing, irrigation, and equipment fluid lines. HVAC technicians, plumbers, and equipment service pros use this fitting type when routing small-diameter tubing in tight spaces where compression or threaded fittings are impractical.

This connector is well suited for residential and light commercial applications including condensate drain lines, water treatment equipment, pneumatic control tubing, and general fluid conveyance systems. The push-to-connect inlet allows fast field installation without tools, while the barbed end creates a reliable mechanical grip on compatible flexible tubing. It is sold and packaged individually, making it an easy single-unit replacement or repair fitting for service calls.

Installation Notes

This fitting is typically installed by HVAC technicians, plumbers, or equipment service professionals. Before installation, shut off the fluid or air supply and relieve all system pressure. Ensure tubing is cut cleanly and squarely for a proper push-to-connect seal. Refer to applicable plumbing or mechanical codes for pressure rating and material compatibility requirements in your jurisdiction.
