Seals & Seal Types

Seals

High performance seals can be designed and manufactured by AFT Fluorotec wherever durability and resistance to chemicals and temperature fluctuations are the norm. Seals can be provided in PTFE and filled PTFE materials designed to give increased performance.
AFT Fluorotec can manufacture seals for most applications. PTFE materials can be selected to meet the particular application and the design can be tailored to suit.

Seals Types

Elastomeric Energiser Material
Selection depends wholly on the service conditions, specifically temperature and media. Options include Viton, Nitrile, Silicone, EPDM and Perfluoroelastomer also Known as Kalrez.

Spring Energiser Material
These would typically be Stainless Steel but for more aggressive environments or to meet NACE approvals, Elgiloy, Hastelloy and Inconel may be selected.

Jacket material is not restricted to just PTFE
Commonly Virgin, Carbon, Graphite, Glass/Moly and Bronze filled PTFE would be used but for applications using non hardened running surfaces Ekonol filled PTFE would be recommended. There are many special blends of PTFE for specific high performance uses and UHMWPE is also commonly used. All material selection is specific to application.
