Mission Rubber 1808013 No-hub Coupling 8 Inch Cast Iron

Product Description

The MISSION RUBBER 1808013 is a standard lightweight no-hub coupling designed for joining cast iron no-hub pipe and fittings in drain, waste, and vent (DWV) piping systems. This coupling uses a neoprene gasket sleeve and stainless steel shield with clamp bands to create a secure, leak-resistant connection without threading or hubbed joints. It is sized for 8-inch nominal cast iron pipe ends and is domestically manufactured. Licensed plumbers and pipefitters install this type of coupling in both new construction and retrofit drainage work.

This coupling is suited for residential and commercial DWV applications where no-hub cast iron pipe is the specified material. Common install scenarios include below-slab drain lines, above-ground stack connections, and underground building sewer runs. The cast iron end style designation confirms fitment for standard no-hub cast iron pipe outside diameters at the 8-inch nominal size. Domestic manufacture supports project specs that require country-of-origin compliance.

Installation Notes

No-hub couplings of this type are installed by licensed plumbers in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off all flow and ensure the pipe is dry before installing. Use a calibrated torque wrench or no-hub torque driver to tighten band clamps to the manufacturer-specified torque for this coupling class. Do not overtighten or undertighten clamp bands, as either condition can compromise the seal.
