The key is the unique combination of materials. A PTFE envelope creates a water and chemical resistant shield that protects two Multi-Seal compressed fibre inserts. With the added rigidity of stainless steel, the gasket delivers the perfect balance of seal strength, crack protection and chemical resistance. Our glass lined vessel gaskets are intended for applications with maximum continuous operating temperatures up to 260 ˚C (500 ˚F).
JA Harrison’s GLVG’S are made up of 3 components, 2 x Multi-Seal inserts which are placed either side of a 1.5mm stainless steel corrugated ring (this prevents the gasket from being blown out) and are then enclosed by a PTFE envelope which has a high chemical resistance, which protects the Multi-seal inserts, and this allows the gasket assembly to work up to a temperature of 260 Degrees C. All 3 components parts are manufactured at our Manchester site which allows us to react to emergencies that occur on site.
