Stiffened Gasket, 3 Feet
This Stiffened Gasket fits Pans/Pan Sets that are 3 feet wide. Raised Flue and Drop Flue Pan Sets employ TWO Stiffened Gaskets: one between the pans and one behind the flue pan.
A Stiffened Gasket prevents cold air from being sucked underneath your pans which would negatively affect boiling rate. They also prevent exhaust from escaping the arch.
The Stiffened Gasket from Smoky Lake contains a strong spine of stainless steel which is then covered with a sleeve of fire resistant, braided rope. The ends of the sleeve are finished off with fire resistant tape to prevent fraying.
