Mission Rubber 1806017 No-hub Coupling 6 Inch

Product Description

The MISSION RUBBER 1806017 is a standard lightweight no-hub coupling designed to join cast iron drain, waste, and vent pipe without the need for hub-and-spigot connections. This coupling uses a neoprene sleeve and stainless steel band clamps to create a leak-resistant mechanical joint suitable for residential and commercial DWV systems. Plumbers and pipefitters install this fitting when connecting no-hub cast iron pipe segments or transitioning between compatible pipe ends. The 6-inch nominal size and cast iron end style make it appropriate for larger-diameter drain and waste lines commonly found in multi-story or high-load plumbing systems.

This no-hub coupling is used in drain, waste, and vent applications where cast iron piping is specified. Typical installations include main building drains, soil stacks, and horizontal waste runs in both new construction and retrofit projects. The lightweight design reduces handling strain during overhead or confined-space installations. It is domestically produced, which may satisfy project specifications requiring domestic-origin materials.

Key Features

• Standard lightweight no-hub coupling for cast iron DWV pipe systems
• 6-inch nominal pipe size accommodates larger drain and waste lines
• Cast iron end style ensures proper fitment with no-hub cast iron pipe
• Neoprene sleeve construction provides a flexible, leak-resistant seal
• Stainless steel band clamp design allows for torque-down installation with a standard torque wrench
• Domestically manufactured for projects with domestic-origin requirements

Compatibility

Designed as an OEM-style replacement and standard fitment for 6-inch nominal no-hub cast iron drain, waste, and vent pipe systems with cast iron end style connections.

Installation Notes

Installation is performed by licensed plumbers following applicable local plumbing codes and CISPI standards for no-hub cast iron systems. Shut off the water supply and ensure the pipe is depressurized before service. Slide the neoprene sleeve over the pipe ends, seat both pipe ends fully into the coupling, and tighten the band clamps evenly to the torque specification printed on the coupling or specified by the manufacturer. Do not overtighten or undertighten the clamps, as either condition can compromise the seal.
