Seals in PTFE and Engineered Thermoplastics

Unilion

With the Unilion® range, James Walker provides industry worldwide with the high-performance answer to fluid sealing problems where conventional products fail to give the integrity or reliability required.

UnilionSpring-energised seals are far from new - we have been manufacturing them since the 1940s. But we now offer a full range of Unilion precision-engineered products that meet the following parameters...

  • Used successfully on applications at up to 103MPa/15,000psi
  • Cryogenic duties down to -260°C
  • Temperature excursions up to +300°C
  • Resistance to corrosive media
  • Efficient dynamic operation following long stationary periods

Based on these operational benefits, we recommend Unilion for applications that preclude the use of more conventional elastomeric/polymeric seals on arduous duties in areas such as...

  • Oil and petrochemical
  • Cryogenic plant
  • Aerospace
  • Food and pharmaceutical processing
  • Automotive and general industry

Moreover, Unilion seals have no storage period limitation. They can safely be held in stock on-site to meet OEM and maintenance requirements.

As a single Unilion can often perform three sealing duties - static, reciprocating and rotary - this can also reduce your stockholding requirements and simplify inventory control.
