A Y Mcdonald Aym-74743-44 1 Mip X Pvc Coupling 1 in

Product Description

The A Y MCDONALD aym-74743-44 1 is a 1-inch MIP x PVC compression coupling designed for connecting male iron pipe threaded fittings to PVC piping systems. This transition fitting allows a plumber or pipefitter to join threaded metal pipe ends directly to PVC compression-style connections without solvent cementing or additional adapters. It is a standard service fitting used in water supply and distribution applications where a transition between metal threaded and plastic pipe systems is required. The compression-style end provides a secure, leak-resistant seal suited for residential and light commercial plumbing work.

This coupling is commonly installed in residential water service lines, irrigation systems, and light commercial plumbing where a transition from threaded metal pipe to PVC is needed. It is appropriate for new installations and retrofit work where existing metal threaded pipe must connect to PVC distribution lines. Licensed plumbers and pipefitters are the primary installers for this type of fitting in potable water and irrigation applications.

Key Features

• 1-inch MIP inlet for direct connection to male iron pipe threaded fittings
• PVC compression outlet eliminates the need for solvent cement at the PVC end
• Transition coupling design bridges threaded metal and plastic PVC piping systems
• Compact coupling form factor simplifies installation in tight spaces

Compatibility

Designed as an OEM-style transition fitting for 1-inch MIP threaded pipe connections to PVC compression piping systems in residential and light commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before beginning work. Hand-tighten the MIP threaded connection first, then use a wrench for final seating — avoid overtightening, which can crack PVC fittings or damage threads. Ensure the PVC pipe end is cut cleanly and squarely before inserting into the compression end to achieve a proper seal.
