FKM O-ring AS568-214

Description

1. Product Overview
   The FKM O-ring AS568-214 is a high-performance fluorocarbon (Viton®) elastomer seal conforming to the AS568 aerospace standard, with a 0.984-inch inside diameter and 3.53mm cross section. Its primary industrial use is as a critical sealing component in harsh chemical, high-temperature, and high-pressure environments across aerospace, automotive, chemical processing, and oil & gas sectors. The key value proposition is its unmatched resistance to heat (up to 205°C/400°F), fuels, mineral oils, strong acids, and oxidative degradation compared to standard elastomers. Strategically, this O-ring is essential for preventing costly leaks, ensuring operational safety, and maintaining equipment integrity in mission-critical industrial systems where sealing failure could result in catastrophic downtime or environmental hazards.
