It creates a positive seal at flange, piston and rod interfaces without added hardware.
Silicone is valued for flexibility that holds at very low temperatures and an exceptionally wide service temperature range. The compound resists extreme heat and cold, many oxidizing chemicals, and weathering. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Exposure to hydrocarbon fuels and oils or concentrated acids will shorten service life.
Maintenance and OEM teams specify it across sanitary process lines, medical devices, and pharmaceutical manufacturing.
Order part number S70431, sold individually. Unit weight is approximately 23.69 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
