Cork Gaskets

These gaskets are a staple for modern industrial gaskets. They are sourced from cork oak trees. Every 9-12 years, the bark can be harvested without harming the tree, making it an excellent environmentally-friendly material.

Cork is also compressible unlike other material that may flow sideways, distort or elongate, cork shows very minimal side flow. This is because of the unique cork cell structure wherein air is entrapped in tiny but flexible walls of the cork cell.

Cork gaskets are also malleable, in the sense that when they are compressed, the air in each cell gets squeezed into smaller spaces, which maintains counter pressure enabling the cork to spring back to original its shape when the force is released. This feature continues to remain intact even after several years.

BOSCO supplies cork gaskets with unique properties like true compressibility, low density, flexibility, surface frictional properties, resistance to liquid penetration, low thermal and electrical conductivity, vibration isolation and more. These continue to remain in the smaller granules of cork and hence it is used in the manufacturing of several specialty products.

Applications

Some industries that use cork gaskets are:

• Electric Motor – Gaskets for shock and vibration control on motor mounts.
• HVAC – Vibration absorbing gaskets for ducts, furnaces and compressors.
• Power & Utility – Gaskets for use in compressors, turbines and engines that require fuel or oil resistant seals and equipment that need vibration control.
• Locomotive – Engine gaskets for filters and fuel lines that require fuel and oil resistance. Gasketing for engine mounts to provide vibration and shock control.
• Material Handling – Gaskets for vibration and shock control.
• Compressor – Oil and fuel-resistant sealing gaskets and shock & vibration dampening gaskets for mountings.
