It resists petroleum oils, ozone and weathering, and extreme cold. Rated temperature range runs from -80°F (-62.2°C) to 350°F (176.7°C) in continuous service. Verify compatibility before use with brake fluids or high-temperature dynamic service.
Maintenance and OEM teams specify it across aerospace and defense, high-altitude equipment, and aviation fuel systems.
Order part number FS70233, sold individually. Unit weight is approximately 3.689 g. Check the compound against your process media, pressure and temperature before committing to a design.
