Product Information

General Information:
High Performance Seals for extreme service conditions:
TFC’s metal seals are generally used in static applications and are designed to provide high fluid sealing levels under the most extreme working conditions.
Our seals are produced from stainless steel or high temperature alloy tubing, strip and wire.

General Properties:

  • Sizes: Diameters from 5mm to 7 metres
  • Temperature: Cryogenic to +750°C
  • Pressure: From ultra high vacuum to over 500 MPa (72500 Psi)
  • Capable of reaching tightness better than 109 mbar.l/s
  • Excellent resistance to corrosion and radiation
  • Maintains elasticity over an extended service life
  • Does not suffer from explosive decompression
  • Radiation resistant
  • Cross section from 0.8mm to 12.5mm
  • Available in circular, race track, oval and other shapes

Quality assured since 1981 ISO 9001:2008 Aerospace AS9100C & AS9120AWith ISO9001: 2015 approval incorporating Design Status, our qualified engineering staff are able to offer a completely free of charge engineering service and are available to assist with part selection, custom design, application requirements, material selection and more.

Applications are discussed in-depth, first-off design data and drawings are submitted for approval to ensure our customers are provided with the correct design, first time. However, on those rare occasions when modifications are necessary, our no-tooling process and flexible manufacturing procedures means the production of prototypes is easily and economically achieved without onerous tooling charges and long lead times.

At TFC we realise that Quality runs through the entire business, not just our products. We have continually invested in the right people to provide the superior market knowledge and customer service.

Our supply chain partners, from manufacturers to logistics and information technology are carefully chosen to ÿt our commitment to quality
