At Kriloha Ltd., we recognize that while pure expanded graphite is a legendary sealer, its inherent fragility can be a liability during the rigors of industrial installation. Large gaskets made of pure graphite can snap or tear under their own weight. To solve this, Kriloha Gaskets developed the Foil-Reinforced Expanded Graphite Gasket. As a leading supplier of high-performance rubber seals and gaskets, we have engineered this product to combine the world-class sealability of graphite with the mechanical “backbone” of stainless steel.
The architecture of this gasket consists of layers of high-purity expanded graphite mechanically or chemically bonded to a thin core of 316L Stainless Steel foil. At Kriloha, we utilize a proprietary bonding process that ensures the graphite remains permanently attached to the metal, even under extreme thermal cycling. The metal foil is invisible once installed, but it provides the necessary radial strength to prevent “blow-out”—a condition where internal pressure forces the gasket material out of the flange.
From a technical perspective, the Kriloha foil-reinforced series offers a significant advantage in Seating Stress Management. Because the foil provides a structural limit, the gasket can handle higher bolt loads than non-reinforced versions without the graphite “cold-flowing” or thinning out excessively. This makes it an ideal “Workhorse Gasket” for standard ASME B16.5 flanges. Furthermore, the 316L foil core provides a secondary layer of chemical protection, ensuring that even if the graphite surface is slightly compromised, the metal barrier remains intact.
As the industry’s top provider, Kriloha Ltd. ensures that our graphite is batch-tested for ultra-low sulfur and halogen content. This is vital because low-quality graphite can cause galvanic corrosion of the metal foil or the flange face itself. By choosing Kriloha, you are guaranteed a high-purity, long-life sealing solution that is easy for technicians to handle on-site, reduces the risk of installation damage, and provides the fire-safe security required for modern industrial safety protocols. Whether you are sealing a simple water line or a complex chemical reactor, our foil-reinforced gaskets deliver the perfect balance of flexibility and strength.
