Verify first
Verify before you commit. Cheap to catch now.
A torn gasket is an invisible leak. Pull the joint apart, smooth the pipe edge, replace the gasket, and reassemble by the manufacturer method.
['Factory-gasketed spiral systems depend on that seal staying intact inside the joint.

Pull it back, deburr/chamfer the cut edge, replace the damaged gasket, use approved lubricant if required, and verify full engagement before fastening.']
