Lamons 4″ Corrugated Metal Gasket (4-Pack)

The **Lamons 4″ Corrugated Metal Gasket with Graphite Facing** delivers a superior seal by combining the flexibility of **flexible graphite** with the structural integrity of a **316 stainless steel core**. This design ensures **low bolt load performance**, making it ideal for applications where minimal clamping force is required—such as irregular flange surfaces or sensitive equipment. The graphite facing provides **excellent resistance to gases, thermal oils, and cryogenic temperatures**, while the corrugated metal core prevents extrusion under pressure.

Certified **fire-safe** (meeting **API and FITT fire test standards**), this gasket maintains reliability in extreme conditions, from **-400°F to 850°F** (with steam resistance up to **1,200°F**). Its **non-stick surface** minimizes flange adhesion, and its **low emission** properties make it suitable for clean environments. With an **inside diameter of 4.5″** and an **outside diameter of 7.125″**, it fits standard 4″ flanges while accommodating irregular surfaces for a **consistent, leak-proof seal**. Each pack includes **four gaskets**, ensuring you have spares for maintenance or bulk applications.
