Parker 72338346 Push-to-connect Tube to Barb Connector

Product Description

The PARKER 72338346 is a push-to-connect tube-to-barb connector designed for joining semi-rigid tubing to flexible hose in fluid transfer systems. The fitting accepts a 3/8 inch stem OD on the push-to-connect end and transitions to a 5/16 inch hose barb OD on the opposite end. It is constructed from bio-sourced Nylon 11 with an EPDM o-ring seal and is rated to 190 psi. Plumbers, HVAC technicians, and fluid systems installers use this fitting wherever a secure, tool-free tube connection to a barbed hose port is required.

This connector is suited for residential and light commercial fluid transfer applications including water lines, pneumatic circuits, and equipment plumbing where a transition from rigid or semi-rigid tubing to flexible hose is needed. The push-to-connect stem end allows fast field installation, making it practical for service work and new construction alike. The white Nylon 11 body is compatible with a range of media handled in typical plumbing and HVAC fluid circuits.

Installation Notes

Installation is performed by plumbers or HVAC technicians. Depressurize and drain the line before removing or installing any fitting. Ensure tubing is cut square and deburred before inserting into the push-to-connect stem to achieve a proper seal. Hose barb connections should be secured with an appropriately rated clamp per applicable IPC or system manufacturer guidelines.
