It compresses into its gland to block fluid or gas migration across a joint.
Silicone is widely chosen for an exceptionally wide service temperature range and flexibility that holds at very low temperatures. The compound resists extreme heat and cold, weathering, and dry heat. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Exposure to steam above its rated range or concentrated acids will shorten service life.
This item meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. You will find this material specified across pharmaceutical manufacturing, sanitary process lines, and electronics and electrical enclosures.
Stocked as S70FDA240 and sold individually. Unit weight is approximately 4.23 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
