Romac 242-127506 Mechanical Joint Accessory Pack 12 in

Product Description

The ROMAC 242-127506 is a mechanical joint accessory pack designed for use with 12-inch ductile iron water main piping systems. It provides the hardware needed to complete a mechanical joint connection in waterworks applications, including components manufactured from ductile iron, 304 stainless steel, and PVC plastic. The pack is UL Listed and conforms to multiple ANSI, ASTM, and AWWA standards. Waterworks contractors and utility crews rely on this type of accessory pack to ensure compliant, leak-resistant mechanical joint assemblies during new installation or repair work on potable water distribution mains.

This accessory pack is intended for waterworks applications on 12-inch pipe, with an actual outside diameter accommodation of 12-3/4 inches, consistent with standard ductile iron pipe dimensions. It is suited for municipal water distribution systems, service lateral connections, and similar pressure piping applications where AWWA C-111 and AWWA C-151 compliance is required. The combination of ductile iron hardware, stainless steel fasteners, and PVC gasket or insert components addresses the corrosion and sealing demands common in buried water service environments.

Key Features

• Fits 12-inch pipe with a 12-3/4 inch outside diameter accommodation
• Multi-material construction: ductile iron body components, 304 stainless steel hardware, and PVC plastic elements
• UL Listed for waterworks applications
• Meets ANSI A21.11, ANSI C111 dimensional and performance standards
• Conforms to AWWA C-111 and AWWA C-151 for mechanical joint fittings and ductile iron pipe
• ASTM A-536 Grade 65-45-12 ductile iron meets published tensile and yield strength requirements

Compatibility

Designed for use with 12-inch ductile iron pipe and fittings meeting AWWA C-151 and AWWA C-909 2002 standards, where mechanical joint connections conforming to AWWA C-111 and ANSI A21.11 are specified.

Installation Notes

Installation should be performed by licensed waterworks contractors or utility crew members familiar with AWWA mechanical joint assembly procedures. Depressurize and isolate the pipeline section before beginning any joint work. Follow AWWA C-111 torque and bolt sequence guidelines for the specific pipe diameter to ensure uniform gasket seating. Inspect all components for damage before assembly, and verify compatibility with the specific pipe outside diameter on site.
