Romac 171-072420000 Cast Lug Repair Clamp 6 Inch Pipe

Product Description

The ROMAC 171-072420000 is a single-section cast lug repair clamp designed to seal leaks and repair damage on 6-inch pipe in pressurized water distribution and transmission systems. The body is constructed from 304 stainless steel and rated to 150 psi. An SBR gasket provides a reliable seal across a clamping range of 6.84 to 7.24 inches. Eight 5/8-inch diameter by 7-inch long bolts with removable lugs secure the clamp evenly around the pipe circumference. This clamp is installed by waterworks and utility contractors as well as licensed plumbing and mechanical crews performing mainline repairs.

This repair clamp is suited for use on 6-inch potable water mains, reclaimed water lines, and pressure transmission piping in residential, commercial, and municipal utility applications. The removable lug design allows hardware replacement without discarding the body. It is commonly used as a fast field repair on cast iron, ductile iron, PVC, and steel pipe where full section replacement is not practical. The 6.84 to 7.24 inch clamping range accommodates standard outside diameters for 6-inch pipe classes.

Key Features

• 304 stainless steel body meets ASTM A240 and A536 material standards
• 150 psi pressure rating for use on pressurized distribution and transmission lines
• SBR gasket material compliant with AWWA C111 and ASTM D2000 MAA 610
• 8-bolt configuration with 5/8-inch diameter by 7-inch long bolts for uniform clamping force
• Removable lugs allow bolt and hardware replacement in the field
• Clamping range of 6.84 to 7.24 inches fits standard 6-inch pipe outside diameters

Compatibility

Designed as an OEM-style repair clamp for 6-inch nominal pipe with an outside diameter between 6.84 and 7.24 inches, including common ductile iron, cast iron, PVC, and steel pipe in that size class.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified waterworks technician following applicable AWWA and local codes. Depressurize and isolate the affected pipe section before applying the clamp whenever system conditions allow. Torque all bolts in a cross pattern to achieve even gasket compression across the full clamping range. Verify the pipe surface is clean and free of debris, corrosion, or sharp edges that could damage the SBR gasket before final tightening.
