Solid PTFE Gaskets

A4 Engineers is a recognised leader in the development, production and delivery of solid PTFE flange gaskets and seals. The seals are designed to deliver excellent purity, low stress to seal, chemical compatibility, as well as reduced creep and cold flow characteristics. Another advantage of these gaskets is their use in a variety of sealing applications, including use with misaligned, damaged, or rough sealing surfaces. These gaskets are produced in all of the standard ANSI flange sizes. Special sizes and thickness are available upon request. The seals are frequently used in applications subject to extremely harsh chemicals. Additionally, the wide range of temperature capabilities of PTFE flange gaskets (from as low as –400°F to as high as 500°F) allow for a broad variety of uses and applications. With advantages such as cost effectiveness on large flanges, ease of flange surface conformability, chemical compatibility, versatility, and low stress to seal, our specialty seals are the logical choice for custom
