Grafoil^® Die-formed Seal Rings

Grafoil^® Die-formed Seal Rings provide reliable, cost-effective sealing in high temperature environments.

Application:
Typical applications are for environments where operating temperatures exceed 400° F. Grafoil^® die-formed seals can be fabricated in a variety of sizes and shapes and are most often used as valve stem packings or as mechanically activated static seals.

Potential Customers:
Valve manufacturers, pump manufacturers, power generation plants including nuclear and petrochemical facilities, and any OEM that requires high-temperature seals.

Design Requirements:
High-temperature systems require sealing performance that elastomer seals cannot provide. Metal seals can offer a solution, but design constraints such as expensive gland surface finishes and high clamping-force requirements often eliminate metal seals from consideration. Grafoil^® die-formed seals offer a performance-proven sealing alternative for those applications where metal seals or traditional elastomers cannot provide a cost-effective answer to the sealing problem.

The Grafoil^® Solution:
Grafoil^® die-formed seals are efficient and economical high-temperature seals. They are resilient, can be configured to many shapes and sizes, and require less mechanical loading than metal seals.

SUMMARY:
For high-temperature sealing where design requirements and cost considerations invalidate metal seals, Grafoil^® die-formed seals are a cost effective sealing solution.

Key Features:

• High-temperature capability (400° to 1600° F)*
• Lower clamping force required to effect seal
• Easy to conform into circular shapes
• Can be formed with metal for added strength
• Compatible with most fluid media
• Economical and safe asbestos replacement
• Design and engineering assistance available
• Certain sizes available without tooling cost

  * Depending upon application and material
