The DO IT BEST 400921 is a heavy-duty red brass hose barb fitting designed to connect polyethylene pipe to a male IPS threaded pipe end. The fitting features a hex shoulder for wrench grip during installation and transitions from a 3/4 inch barbed insert end to a 3/4 inch male IPS (MIP) threaded end. Wetted surfaces are manufactured to contain no more than 0.25% weighted average lead content, meeting lead-free compliance standards required in potable water applications. Plumbers and irrigation professionals install this type of adapter where poly pipe meets a threaded fitting in both residential and light commercial settings.
This fitting is suited for use in polyethylene pipe systems, including residential water service lines, irrigation supply lines, and rural water distribution runs. The insert-style barb end grips the inner diameter of poly pipe and is secured with an appropriate clamp or crimp ring. The male IPS thread end connects to standard threaded pipe, valves, or other fittings. It is a common component in below-grade and above-grade potable water and irrigation installations.
Designed as an OEM-style replacement and standard-use fitting for 3/4 inch polyethylene pipe systems with male IPS threaded connections in potable water and irrigation applications.
Installation is typically performed by a licensed plumber or qualified irrigation technician. Shut off the water supply and relieve system pressure before making any connections. Thread sealant tape or compound should be applied to male threads in accordance with local plumbing codes before tightening. Secure the barb end to polyethylene pipe with a properly rated clamp or crimp ring rated for the pipe diameter and system pressure.
