B38;K Llc 57545 Steel Insert Adapter 1 Inch Male Npt

Product Description

The B38;K LLC 57545 is a 1-inch male pipe thread steel insert adapter designed for use with plastic pipe systems. This fitting creates a threaded male connection at the end of a plastic pipe, allowing it to mate with standard female-threaded fittings or valves. The steel construction provides durability at the threaded joint while maintaining compatibility with plastic pipe bodies. It measures approximately 3.2 inches in length and 1.3 inches in both height and width. Plumbers and pipefitters install this adapter where a plastic line must transition to a threaded metal connection in water supply, irrigation, or light commercial plumbing applications.

This insert adapter is suited for residential and light commercial plumbing installations where plastic pipe — such as PVC or polyethylene — requires a male threaded steel termination. Typical applications include pump connections, valve hookups, and supply line assemblies. The male pipe thread configuration follows standard NPT sizing for 1-inch pipe, making it compatible with widely available threaded fittings in plumbing supply systems.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and relieve system pressure before making or breaking any pipe connections. Use appropriate pipe sealant or thread tape on the male NPT threads per local plumbing code requirements. Do not overtighten threaded connections into plastic fittings, as this can cause cracking.
