Mission Rubber 1810019 No-hub Coupling 10 Inch Cast Iron

Product Description

The MISSION RUBBER 1810019 is a standard lightweight no-hub coupling designed to join cast iron no-hub pipe sections without threaded or bell-and-spigot ends. The coupling uses a neoprene gasket and stainless steel shield and clamps to create a leak-resistant, mechanically secure joint in gravity-drain drainage, waste, and vent (DWV) systems. At 10 inches nominal pipe size, this fitting is suited for large-diameter drain lines found in commercial and multi-family residential plumbing systems. Licensed plumbers and pipefitters are the primary installers of this type of fitting.

No-hub couplings are used in above-ground and below-slab cast iron DWV installations where traditional hub-and-spigot joining is not practical. The 1810019 is designed for 10-inch nominal cast iron no-hub pipe, making it appropriate for main building drains, large horizontal runs, and stack connections in commercial buildings, hospitals, schools, and multi-family residential construction. It is domestically produced, which makes it a common specification on public and institutional projects that carry domestic-manufacture requirements.

Key Features

• Standard lightweight no-hub design for cast iron DWV pipe connections
• 10-inch nominal pipe size for large-diameter drain line applications
• Cast iron end style for compatibility with no-hub cast iron pipe
• Domestically manufactured, suitable for Buy American and domestic-content specifications
• No threading or hub required, reducing installation time on large-diameter runs

Compatibility

Designed as an OEM-style replacement coupling for 10-inch nominal no-hub cast iron DWV pipe systems following CISPI and ASTM standards for no-hub pipe and fittings.

Installation Notes

Installation of no-hub couplings on 10-inch cast iron pipe is performed by licensed plumbers following applicable local plumbing codes and CISPI 310 torque specifications for no-hub shielded couplings. De-energize or shut off all systems and ensure the line is clear of flow before cutting into an existing drain line. Use a calibrated torque wrench set to the coupling manufacturer's recommended torque value to seat the clamps evenly and avoid over-tightening the shield. Support large-diameter cast iron pipe runs per code to prevent joint stress after installation.
