The Turcon® Variseal® HF is a single acting sealing element optimized for sealing high-pressure fluid and gas. The high spring load of the helical spring ensures effective sealing even in extremely low temperature applications. These helical spring seals are ideal for slow moving and static applications or in a vacuum sealing applications.The chemical resistance of the Turcon® material and metallic helical spring gives almost universal compatibility with fluids or chemicals and its wide temperature range allows it to be used under extreme conditions. In addition, the Turcon® Variseal® HF has unlimited shelf life. Illustrated as a face seal, it is also available both in piston and rod configurations in metric and AS4716 sizes.
