SS Stamped Dual Duro PVC

SS Stamped Dual Duro PVC

A complex, encapsulated coextrusion of two types of flexible PVC.  Stainless steel is first punched, then roll formed, then the U-channel is coated with a more rigid PVC.  A co-extruded bulb of flexible PVC is added to the part, creating a flexible yet highly-specific seal.
