A Y Mcdonald Aym-74743-44 3/4 Mip X Pvc Coupling

Product Description

The A Y MCDONALD aym-74743-44 3/4 is a male iron pipe (MIP) to PVC compression coupling designed to transition between a threaded metal pipe connection and a PVC compression fitting in a single assembly. This type of fitting allows a plumber to connect a 3/4-inch MIP threaded pipe to a PVC compression line without solvent welding or additional adapters. It is commonly used in water service, meter set, and distribution piping applications where a secure, leak-resistant mechanical connection is required. Licensed plumbers and water service technicians are the primary installers of this fitting type.

This coupling is suited for residential and light commercial water service installations where a transition from threaded iron or brass pipe to PVC water service tubing is needed. Typical applications include water meter connections, main line service entry points, and retrofit or repair work where existing threaded iron pipe terminates and PVC distribution continues. The 3/4-inch size is a standard dimension for residential water service and branch supply lines.

Key Features

• MIP x PVC compression end configuration allows threaded-to-PVC transition in a single fitting
• 3/4-inch size matches standard residential water service and branch line dimensions
• Compression connection on PVC end eliminates the need for solvent cement or heat tools
• Mechanical assembly supports use in confined or wet work environments

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 3/4-inch MIP threaded pipe to PVC compression water service applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and relieve line pressure before beginning any fitting work. Ensure the MIP threads are clean and undamaged before engagement, and use appropriate thread sealant on the threaded end per local code. Do not overtighten the compression nut, as this may deform the PVC tubing or damage the compression seat.
