Echelon-HF™ Gasket

Echelon-HF™Specifically designed for Hydrofluoric Acid (HF)

Description and Applications

Specifically designed for Hydrofluoric Acid (HF), to safely seal an extremely dangerous chemical, as well as where crevice corrosion is a concern, Teadit®'s Echelon-HF™ Gasket is a superior choice. This design is based on an ASME B16.20 spiral wound (primary seal), with a camprofiled Monel® inner ring, providing all the advantages of an inner ring and ePTFE facing with the added benefit of creating a secondary seal that extends towards the bore of the pipe.

Application
The Echelon-HF™ gasket is specifically engineered for use in HF Alkylation service, where carbon steel flanges are highly susceptible to severe crevice corrosion. Our standard, field-proven configuration features an oxidation-inhibited graphite filler in the spiral wound portion, combined with an ePTFE facing. This design, which has an integrated Collar and Inner Ring, delivers enhanced protection against corrosion in one of the most hazardous chemical processing environments.
