Nibco PX00548G Barbed Tube Insert Coupling 3/4 in

Product Description

The NIBCO PX00548G is a barbed tube insert coupling designed for use in push-fit and barbed tubing systems. Molded from polypropylene, this fitting provides a lightweight and corrosion-resistant connection point for joining sections of flexible tubing. The 3/4 inch thread size makes it a common choice for residential and light commercial plumbing, irrigation, and fluid transfer applications. Licensed plumbers and irrigation technicians install this type of fitting when making inline tube-to-tube connections without the need for solvent cement or metal hardware.

This insert coupling is suited for use in PEX, polyethylene, and other flexible tubing systems where a barbed push-in or barbed compression connection is required. Its polypropylene construction resists common chemicals and moisture, making it appropriate for both indoor plumbing rough-in work and outdoor irrigation line repairs. The black color coding can assist with identification in multi-line installations. This fitting is sold in a package quantity of 5 units.

Installation Notes

Installation of barbed tube insert couplings is typically performed by licensed plumbers or irrigation technicians. Shut off the water supply and relieve line pressure before cutting or disassembling any tubing section. Ensure the tubing end is cut square and fully seated over the barbs before applying a crimp ring or clamp per applicable IPC or local plumbing code requirements. Do not exceed the pressure or temperature ratings of the connected tubing system.
