Questions about this item

How is the three-bolt repair clamp positioned and tightened on a 3 1/2 inch pipe?

Center the 9-inch stainless steel body over the damaged section, insert all three 7/16-inch bolts through the lugs, add the supplied nuts and washers, then tighten the bolts evenly in a cross pattern to seat the gasket without distortion.

What part of the clamp will need inspection or replacement after extended service?

The 304 stainless steel band resists corrosion, but the rubber gasket inside the 9-inch length can harden or crack over time; check it during routine maintenance and replace the gasket if sealing performance drops.
