Mission Rubber 1412220 Repair Coupling 12 Inch

Product Description

The MISSION RUBBER 1412220 is an adjustable shielded repair coupling designed for joining or repairing drain, waste, and vent piping where dissimilar pipe materials meet. The MR02 ARC series accommodates a 12-inch nominal pipe size with a Clay x Cast Iron/Plastic end style configuration, making it well suited for transitions between clay sewer pipe and cast iron or plastic pipe sections. Licensed plumbers and underground utility contractors install this coupling during sewer line repairs and rehabilitation work where replacing full pipe runs is not practical or cost-effective.

This coupling is intended for residential and commercial drain, waste, and vent applications, including buried sewer laterals and gravity-flow drain systems. The adjustable shielded design accommodates minor variations in outside pipe diameter, which is common when working with aged clay pipe that may have irregular dimensions. It is a domestically produced fitting suited for use in repair scenarios where access is limited and a bolted shielded coupling is required to maintain alignment and joint integrity.

Key Features

• Adjustable design accommodates minor outside diameter variation in field conditions
• Shielded construction provides full circumferential coverage for a secure, leak-resistant joint
• 12-inch nominal size covers large-diameter sewer lateral and main line repair applications
• Clay x Cast Iron/Plastic end style enables transitions between dissimilar pipe materials
• Domestically manufactured fitting

Compatibility

Designed as an OEM-style repair coupling for 12-inch nominal clay to cast iron or plastic pipe transitions in gravity-flow drain, waste, and vent systems.

Installation Notes

Installation is performed by licensed plumbers in accordance with the International Plumbing Code and applicable local amendments. Confirm pipe outside diameters at both ends before selecting the coupling to ensure the adjustable range is appropriate. Clean and deburr pipe ends and remove any soil or debris from the joint area before positioning the coupling. Follow the manufacturer's bolt torque sequence to achieve uniform gasket compression around the full circumference of both pipe ends.
