Do It Best 425123 3/4 in Insert X 3/4 in Mip Steel Adapter

Product Description

The DO IT BEST 425123 is a galvanized steel insert adapter designed to transition between polyethylene pipe and male iron pipe (MIP) threaded connections. The insert end accepts 3/4-inch polyethylene pipe, while the 3/4-inch MIP threaded end connects to standard threaded fittings and valves. Galvanized steel construction provides corrosion resistance suited to buried or exposed plumbing installations. This fitting is installed by licensed plumbers and experienced pipe fitters working on water distribution, irrigation, and utility supply lines where poly pipe meets threaded steel or brass components.

This adapter is commonly used in residential and light commercial plumbing applications where polyethylene supply lines connect to threaded metal fittings, valves, or service entry points. Typical installation scenarios include well water systems, underground water service laterals, and irrigation mainlines where a transition from flexible poly pipe to a rigid threaded connection is required.

Key Features

• 3/4-inch insert end sized for standard polyethylene pipe
• 3/4-inch MIP threaded end for connection to standard threaded fittings
• Galvanized steel construction for corrosion resistance in wet and buried environments
• Designed for leak-free, secure poly-to-threaded transitions
• Suitable for water distribution, irrigation, and utility supply line applications

Compatibility

Designed as an OEM-style replacement fitting for use with 3/4-inch polyethylene pipe in residential and light commercial water supply and irrigation plumbing systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and relieve system pressure before disassembling any fittings. The insert end is secured to polyethylene pipe using an appropriate clamp or crimp ring rated for the pipe size and pressure rating of the system. Apply thread sealant tape or compound to the MIP threads before making up the threaded connection.
