A waffle gasket has more gasket surface area than a flat gasket. This results in a much longer leak path and a more secure seal.
High contact pressure is created when the Quick-Clamp with a waffle gasket is tightened around a pipe. When a conventional smooth gasket is tightened around a pipe the contact force is spread over the entire gasket. With a waffle gasket the contact force is concentrated at points on the seal. The result is a tighter, more secure seal.
Gasket strength is improved with a waffle gasket because the waffle ribbing reduces gasket flow. More of the gasket stays under pressure and the integrity of the seal is not reduced.
The Quick-Clamp repair band now features an improved waffle gasket design. The new design ensures a leak-tight and secure seal.
