Mission Rubber 1802024 No-hub Coupling 2x1-1/2 in Cast Iron

Product Description

The MISSION RUBBER 1802024 is a standard lightweight no-hub coupling designed to connect cast iron drain, waste, and vent pipe sections without threaded or hub-style joints. It joins a 2-inch nominal pipe to a 1-1/2-inch nominal pipe using a stainless steel clamp band and neoprene sleeve, creating a flexible, leak-resistant connection. This coupling is domestically produced and suited for below-grade and above-grade DWV installations. Licensed plumbers and pipefitters install this fitting as part of residential and light commercial drain systems where no-hub cast iron pipe is the specified material.

This coupling is used in residential and light commercial plumbing applications where cast iron no-hub DWV pipe requires a transition from 2-inch to 1-1/2-inch nominal pipe. Typical install scenarios include sanitary drain lines, vent stacks, and waste branch connections in new construction and retrofit work. The lightweight construction reduces handling fatigue during overhead or confined-space installation. Domestic manufacturing supports projects with domestic content requirements.

Key Features

• Transitions 2-inch nominal to 1-1/2-inch nominal no-hub cast iron pipe
• Standard lightweight construction for easier handling in tight or overhead spaces
• Cast iron end style for compatibility with standard no-hub DWV pipe
• No-hub design eliminates the need for threaded or bell-and-spigot joints
• Domestically manufactured

Compatibility

Designed as an OEM-style replacement coupling for standard no-hub cast iron DWV pipe systems requiring a 2-inch to 1-1/2-inch nominal transition.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and CISPI standards for no-hub cast iron pipe systems. Shut off water supply and ensure the drain line is clear before beginning work. Torque the stainless steel clamp bands with a calibrated torque driver to the tool manufacturer specification printed on the coupling band. Do not overtighten, as this can deform the neoprene sleeve and compromise the seal.
