Krausz 272-56-0087-10w Pipe Repair Clamp 9 Inch Ss

Product Description

The KRAUSZ 272-56-0087-10w is a full stainless steel pipe repair clamp designed to seal leaks and repair damaged pipe sections in pressurized water distribution systems. The clamp features an EPDM seal rated for service temperatures from -20 degrees F to 180 degrees F, making it suitable for a wide range of operating conditions. The sleeve measures 9 inches in length and is sized for pipe outside diameters from 3.42 inches to 4.25 inches, covering nominal 3-inch pipe. Licensed plumbers and waterworks contractors install this clamp as a fast, durable field repair on municipal and commercial water mains.

This repair clamp is used on nominal 3-inch water distribution pipe in municipal, commercial, and industrial applications. The all-stainless-steel construction resists corrosion in direct-burial and exposed installations. Its EPDM gasket provides a reliable seal against water, making it appropriate for potable water systems that require NSF 61 and NSF 372 listed components. The 9-inch sleeve length provides adequate coverage for cracks, holes, and damaged pipe joints common in cast iron, ductile iron, and PVC distribution lines.

Installation Notes

Installation is typically performed by licensed plumbers or waterworks technicians. Depressurize and isolate the affected pipe section before applying the clamp whenever possible, following applicable IPC and local water authority requirements. Clean the pipe surface in the repair area to remove debris, scale, or sharp edges that could damage the EPDM seal. Tighten all bolts evenly in a crossing pattern to ensure uniform gasket compression; refer to AWWA C230 guidelines for bolt torque procedures.
