Mission Rubber Company 6222m8g No-hub Coupling 6 Inch

Product Description

The MISSION RUBBER COMPANY 6222m8g is a 6-inch standard no-hub domestic coupling designed for joining cast iron soil pipe and fittings in drain, waste, and vent (DWV) systems. This flexible coupling uses a neoprene or elastomeric sleeve secured by stainless steel bands and a torque clamp to create a leak-resistant, vibration-dampening connection without the need for hub-and-spigot joinery. It is a domestically manufactured coupling intended for use by licensed plumbers and pipefitters in both new construction and repair applications.

This coupling is suited for residential and light commercial plumbing installations where no-hub cast iron pipe systems are specified. It is commonly installed in underground, above-grade, and in-wall DWV configurations. The 6-inch size accommodates standard 6-inch no-hub pipe and fitting ends. Cross-reference designations include Ideal 6222M8G and Mission 1806017, allowing straightforward sourcing and replacement verification on the job site.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Power tools are not required, but a calibrated torque wrench or driver is recommended to achieve proper clamp band seating without over-torquing the sleeve. Ensure pipe ends are clean, free of burrs, and seated fully into the coupling sleeve before tightening bands. Inspect the elastomeric sleeve for cuts or deformation before installation.
