Spring‑energised seals

Spring-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 103 MPa/15000 psi
• 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 spring energised 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.
