Jcm Industries 241-0420 Metal Bolted Coupling 3 Inch

Product Description

The JCM INDUSTRIES 241-0420 is a Quantum series metal bolted coupling designed for joining pipe sections in water distribution, wastewater, and industrial piping systems. It accommodates outside diameters from 3.46 inches to 4.21 inches, making it suitable for nominal 3-inch pipe across a range of pipe materials and standards. The bolted construction allows field technicians to achieve a secure, leak-resistant mechanical connection without welding or threading. Plumbers, pipefitters, and waterworks contractors typically install this type of coupling during main repairs, tie-ins, and system extensions.

The 241-0420 is applied in residential, commercial, and municipal piping scenarios where a reliable mechanical coupling is needed to connect, repair, or extend a nominal 3-inch line. Its adjustable outside diameter range of 3.46 to 4.21 inches accommodates dimensional variation between pipe standards, including ductile iron, cast iron, steel, and PVC pipe of comparable OD. This makes it a practical choice when transitioning between pipe materials or replacing a damaged section in the field.

Key Features

• Fits pipe outside diameters from 3.46 inches to 4.21 inches on a nominal 3-inch line
• Quantum series metal construction for durability in pressurized piping applications
• Bolted design allows controlled, adjustable tightening during installation
• Accommodates cross-material connections where pipe OD standards differ
• Order increment of 1 for single-unit procurement

Compatibility

Designed as an OEM-style mechanical coupling for nominal 3-inch pipe with outside diameters between 3.46 inches and 4.21 inches, compatible with pipe materials that fall within that OD range including ductile iron, cast iron, steel, and PVC.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters. Before installation, depressurize and isolate the line section being serviced in accordance with local plumbing codes and AWWA guidelines. Bolt fasteners evenly in an alternating pattern to achieve uniform gasket compression. Do not over-torque bolts beyond the fitting manufacturer's published specification.
