Midland Industries 970819 Reducing No-hub Coupling 2x1.5in

Product Description

The MIDLAND INDUSTRIES 970819 is a reducing no-hub coupling designed to connect drainage, waste, and vent (DWV) piping at two different diameters in a single fitting. It transitions a 2-inch no-hub pipe to a 1-1/2-inch no-hub pipe using a rubber sleeve and a 316 stainless steel band assembly. The coupling is rated for 4.3 psi and handles temperatures from -30 degrees F to 140 degrees F, making it appropriate for standard residential and light commercial DWV applications. Licensed plumbers use this coupling during new construction and retrofit drain line work where a diameter change is needed without soldering, threading, or gluing.

This reducing coupling is suited for residential and light commercial plumbing systems where cast iron, plastic, or clay DWV pipe must be joined at differing nominal sizes. Typical scenarios include connecting branch drain lines to main stack runs, adapting existing pipe runs during renovation, and making field repairs on mixed-material drain systems. The no-hub design allows installation in confined spaces where traditional hubbed fittings would be impractical.

Key Features

• Reduces 2-inch no-hub connection to 1-1/2-inch no-hub connection in a single fitting
• 316 stainless steel band provides corrosion resistance in wet and underground environments
• Rubber sleeve creates a leak-resistant, flexible seal between dissimilar or same-material pipes
• Rated to 4.3 psi working pressure for standard DWV service
• Temperature range of -30 degrees F to 140 degrees F suits typical drain line conditions
• Standard installation torque of 60 in-lb for consistent, repeatable band clamp tightening

Compatibility

Designed as an OEM-style no-hub reducing coupling for standard 2-inch to 1-1/2-inch DWV pipe connections in residential and light commercial plumbing systems.

Installation Notes

Installation is performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and ensure the drain line is depressurized and clear before beginning work. Pipe ends should be clean, deburred, and free of grease or debris before the rubber sleeve is seated. Tighten band clamps to the specified torque using a torque-controlled nut driver or torque wrench - do not over-tighten, as this can damage the rubber sleeve.
