Nibco PX00618G Barbed Tube Insert Elbow 1 Inch

Product Description

The NIBCO PX00618G is a single-barb tube insert elbow fitting designed for use in fluid transfer and plumbing piping systems. Molded from polypropylene, this fitting connects flexible tubing at a 90-degree change of direction without the need for threaded connections or clamps beyond the barb retention. The single-barb design allows the tubing to seat firmly over the fitting end, creating a secure, low-profile connection point. At a thread size of 1 inch, it suits common tubing diameters found in residential and light commercial applications. The black polypropylene construction resists corrosion and is lightweight, making it practical for a wide range of fluid system installations handled by plumbers and pipefitters.

This insert elbow is suited for use in residential and light commercial plumbing, irrigation, hydronic, and fluid distribution systems where flexible tubing requires a directional change. It is installed in locations where rigid pipe transitions are impractical or where flexible tubing runs need to navigate corners or tight spaces. Typical applications include potable water distribution, irrigation manifolds, and low-pressure fluid transfer lines. The polypropylene material is compatible with a broad range of non-aggressive fluids. It is commonly installed by licensed plumbers, pipefitters, or irrigation technicians during new construction or repair work.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch flexible tubing in residential and light commercial plumbing, irrigation, and fluid transfer piping systems.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the fluid system fully before removing existing fittings or cutting into any tubing run. Insert the barbed end fully into the tubing until the tubing seats against the fitting shoulder to ensure a leak-free connection. Follow local plumbing codes, including applicable IPC requirements, for approved fitting materials and pressure ratings before installing in potable water systems.
