At Kriloha Ltd., we understand that “Chemical Resistance” and “Structural Strength” are often at odds. In the world of specialty chemicals, you need the inertness of PTFE, but you also need the mechanical “memory” of a metal gasket. The Kriloha PTFE Envelope Gasket is our solution for this engineering challenge. As a premier global supplier of industrial seals, Kriloha Gaskets has mastered the art of the “Shielded Seal,” protecting your high-performance cores with a fortress of virgin PTFE.
The architecture of an Envelope Gasket is defined by its “Shield.” We utilize a precision-machined or slit PTFE envelope—typically in a “Y-Type” (Slit) for standard piping or a “U-Type” (Milled) for large-diameter reactors. Inside this shield, we place a core tailored to your specific mechanical needs. For example, a Corrugated Stainless Steel core provides the spring-back needed for thermal cycling, while a Flexible Graphite core offers excellent conformability for pitted flanges. This hybrid approach means the PTFE handles the chemistry, while the core handles the physics.
Manufacturing these gaskets at Kriloha requires absolute dimensional control. Because the envelope must fit snugly over the core without “bunching,” we maintain tolerances within +/- 0.2mm. We use only 100% Virgin PTFE for our envelopes to ensure zero porosity. This prevents “wicking,” where chemicals might otherwise seep through the PTFE over time and attack the internal core. By choosing Kriloha Ltd., you are investing in a product that eliminates the compromises of pure plastic seals, providing the chemical invincibility and mechanical stamina your facility demands.
