Krausz 274-56-0113-10w Pipe Repair Clamp 4 in 15 in Ss

Product Description

The KRAUSZ 274-56-0113-10w is an all stainless steel pipe repair clamp designed to seal leaks and breaks on 4-inch nominal water and wastewater piping. The clamp spans 15 inches in length and fits outside diameters ranging from 4.47 inches to 5.27 inches. An EPDM elastomeric seal provides a reliable, flexible gasket that accommodates minor pipe surface irregularities. The operating temperature range runs from -20 degrees F to 180 degrees F, making it suitable for buried and above-grade installations in a wide range of climates. Licensed plumbers and water distribution crews install this fitting for emergency repairs and planned rehabilitation work.

This clamp is applied in municipal water distribution, residential and commercial service line repair, and industrial piping systems where a full-encirclement repair is required. The all stainless steel body and hardware resist corrosion in direct-burial and wet environments. The EPDM seal is rated for potable water contact under NSF 61 and NSF 372, and the clamp meets AWWA C230 standards for saddles and clamps used in water service applications.

Compatibility

Designed as an OEM-style repair clamp for 4-inch nominal pipe with outside diameters between 4.47 inches and 5.27 inches, including common pipe materials used in water distribution and service line applications.

Installation Notes

Installation is typically performed by licensed plumbers or water distribution technicians in accordance with local plumbing codes and AWWA guidelines. Depressurize and isolate the pipe section before positioning the clamp when conditions allow. Center the EPDM seal over the damaged area before evenly torquing the stainless steel fasteners in an alternating pattern to achieve uniform gasket compression. Do not over-torque fasteners, as this may distort the seal or damage the pipe wall.
