Mission Rubber 1801018 No-hub Coupling 1-1/2 Inch

Product Description

The MISSION RUBBER 1801018 is a standard lightweight no-hub coupling designed to join no-hub cast iron soil pipe and fittings in drain, waste, and vent (DWV) systems. The 1-1/2 inch nominal size and cast iron end style make it a direct-fit solution for standard no-hub piping configurations. A stainless steel band clamp and neoprene gasket provide a secure, leak-resistant connection. Licensed plumbers install this coupling in both new construction and repair applications where hub-and-spigot joinery is not present.

This coupling is used in residential and light commercial DWV piping systems where no-hub cast iron pipe is specified. Typical install scenarios include drain line repairs, stack connections, and transitions within concealed or exposed sanitary drainage configurations. The lightweight design reduces handling fatigue in overhead and confined-space installations.

Key Features

• 1-1/2 inch nominal size fits standard no-hub cast iron pipe and fittings
• Cast iron end style for direct connection to no-hub cast iron DWV pipe
• Lightweight construction for easier handling in tight or overhead spaces
• Standard no-hub coupling format compatible with conventional band clamp torque tools
• Domestic manufacture

Compatibility

Designed as an OEM-style replacement coupling for 1-1/2 inch nominal no-hub cast iron DWV pipe and fittings in standard sanitary drainage systems.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off water flow and ensure the pipe ends are clean, debris-free, and properly deburred before seating the neoprene gasket. Use a calibrated torque wrench or no-hub torque driver to tighten the stainless steel band clamp to the manufacturer-specified value listed on the coupling packaging. Do not overtighten, as this can damage the neoprene gasket and compromise the seal.
