Midland Industries 195474 Flexible Reducing Coupling 4x1.5in

Product Description

The MIDLAND INDUSTRIES 195474 is a flexible reducing coupling designed to connect pipes of two different diameters within drain, waste, and vent piping systems. It transitions from a 4-inch connection on one end to a 1-1/2-inch connection on the other, using a rubber body that absorbs minor misalignments and vibration. A stainless steel band clamp secures each end to the pipe. Rated to 150 psi and tested across a temperature range of -30 to 140 degrees F, this coupling suits both buried and above-ground residential and light commercial plumbing applications. Licensed plumbers are the primary installers.

This coupling is suited for Schedule 40 piping systems where a size reduction is needed between a larger drain line and a smaller branch or fixture connection. The rubber construction accommodates slight angular and axial offsets that rigid fittings cannot tolerate, making it practical in retrofit and repair scenarios where pipe ends do not line up perfectly. It carries a 1-1/2 in to 11-1/2 thread specification and is commonly used in residential drain and vent rework, commercial restroom rough-in, and utility room plumbing.

Key Features

• Reduces from 4-inch pipe to 1-1/2-inch pipe in a single fitting
• Rubber body flexes to accommodate minor pipe misalignment
• Stainless steel band clamps resist corrosion at each connection point
• Rated to 150 psi for use in pressurized drain and waste lines
• Operating range of -30 to 140 degrees F suits most indoor and buried applications
• Schedule 40 rated for compatibility with standard-wall plastic and cast iron pipe

Compatibility

Designed as an OEM-style replacement flexible reducing coupling for Schedule 40 drain, waste, and vent piping systems requiring a 4-inch to 1-1/2-inch transition.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code. Shut off water supply and relieve system pressure before cutting into any active line. Slide the stainless steel band clamps over the pipe ends before seating the rubber body, then tighten clamps evenly to ensure a leak-free seal. Do not over-torque the band clamp fasteners, as this can distort the rubber body and compromise the seal.
