Mission Rubber 1805019 No-hub Coupling 5 Inch Cast Iron

Product Description

The MISSION RUBBER 1805019 is a standard lightweight no-hub coupling designed for joining cast iron drainage, waste, and vent pipe without the need for hub connections. It uses a stainless steel shield and clamp band assembly to compress a neoprene gasket around the pipe ends, creating a leak-resistant, shear-resistant joint. The coupling accommodates 5-inch nominal cast iron pipe ends and is domestically manufactured. Licensed plumbers and pipefitters install this fitting during new construction and retrofit drain-waste-vent work.

No-hub couplings like the 1805019 are standard in residential and commercial plumbing systems wherever cast iron DWV piping is used. Typical applications include underground and above-grade drainage runs, vertical stacks, and horizontal branch connections. The lightweight construction reduces handling fatigue in overhead or confined-space installations. This coupling is suited for any application requiring a no-hub connection on 5-inch cast iron pipe.

Key Features

• 5-inch nominal size for cast iron no-hub pipe connections
• Standard lightweight design reduces installation fatigue in overhead and confined-space work
• Cast iron end style accommodates standard no-hub pipe OD tolerances
• Domestically manufactured to CISPI and ASTM standards typical for no-hub couplings
• Neoprene gasket sleeve compressed by stainless steel shield and clamp band assembly

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 5-inch nominal cast iron no-hub drainage, waste, and vent piping systems.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code and applicable local codes. Shut off flow and ensure the pipe is clean, dry, and free of burrs or sharp edges before seating the neoprene gasket. Use a calibrated torque wrench or no-hub torque driver to tighten clamp bands to the torque value specified by the coupling manufacturer. Do not overtighten, as this can tear the gasket or deform the shield.
