Viton is a high-performance fluoroelastomer that maintains structural stability in the presence of oxygen, making it the industry standard for O2-compatible life-support equipment. By choosing Viton 90, you are selecting a seal that resists chemical attack and provides consistent elastic memory throughout its service life.

Its Shore A hardness rating provides the ideal balance between deformation-resistance under pressure and the ability to conform to irregular sealing surfaces. This ensures a leak-free environment that is maintained throughout the life of the O-ring, even under the significant thermal shifts experienced during diving excursions.
