MS52000-1 is a low-temperature synthetic rubber flat gasket designed for use with 97 series flange-mounted receptacles. This gasket is engineered to provide superior sealing performance in extremely low-temperature environments, retaining its resiliency and sealing characteristics even at temperatures as low as -67°F. The gasket maintains a pressure differential seal of 30 psi at these extreme temperatures, making it ideal for applications requiring reliable waterproof and pressure sealing in harsh cold conditions. Its synthetic rubber material composition ensures durability and consistent performance across demanding aerospace, military, and industrial applications where temperature extremes and environmental protection are critical requirements.
