Mission Rubber 1408236 Unshielded Sewer Coupling 8x6 in

Product Description

The MISSION RUBBER 1408236 is an unshielded flexible sewer coupling designed to connect dissimilar pipe materials in drain, waste, and vent (DWV) systems. It accommodates an 8-inch nominal clay pipe end to a 6-inch nominal cast iron or plastic pipe end, making it a practical solution where pipe sizes and materials change within the same run. The flexible rubber sleeve conforms to both pipe ends, creating a watertight seal without the need for shielded band clamps. Licensed plumbers typically install this coupling during sewer repair, rehab, or new construction tie-in work.

This coupling is suited for residential and light commercial sewer applications where clay tile pipe meets cast iron or PVC/ABS pipe. Common scenarios include lateral sewer line repairs, municipal connection transitions, and building drain tie-ins where older clay infrastructure meets modern plastic or cast iron pipe. The 8 x 6 inch size addresses a common mismatch found in aging sewer systems being partially replaced or upgraded.

Key Features

• Unshielded design for straightforward coupling without external band hardware
• Accommodates two different nominal pipe sizes: 8 inches and 6 inches
• Bridges dissimilar materials: clay pipe to cast iron or plastic pipe
• Flexible rubber construction conforms to pipe ends for a watertight seal
• Domestically manufactured

Compatibility

Designed to connect 8-inch nominal clay pipe to 6-inch nominal cast iron or plastic (PVC/ABS) pipe in DWV and sewer applications.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or locally adopted plumbing codes. Before installation, isolate the sewer line and ensure both pipe ends are clean, free of debris, and cut square. Slide the rubber coupling over each pipe end and seat it fully before securing any clamps. Do not stretch the sleeve beyond its rated range or install over cracked or structurally compromised pipe ends.
