Effective protection for connector seals and gaskets in the engine compartment environment

Maximize the effectiveness of your electrical connector seals with the proven protection of Silastic® brand silicone high-consistency rubber (HCR), fluorosilicone rubber (FSR), and liquid silicone rubber (LSR) elastomers.

• Create protective perimeter seals to exclude moisture,  dust, oil, and fuel from critical connections
• Maintain mechanical performance at wide temperature ranges, from -40 to 200º C (-40 to 392º F)
• Ensure electrical insulation exceeds dielectric specifications

Simplified assembly and maintenance

Self-lubricating characteristics of Silastic elastomers provide:  

• Trouble-free threading of cables and components through grommets and mat seals
• Easy insertion and extraction of gaskets and connector seals

Withstand fuel, oil, and solvents

• Enhance your fuel connectors and gaskets with high-performance Silastic fluorosilicone rubber (FSR) elastomers to resist fuel, oil, and solvents that would degrade organic rubbers

Improve your process efficiency

• Silastic LSR elastomers enable advanced mold design and process automation
• Material characteristics permit state-of-the-art fabricating methods such as overmolding of plastic connectors
• Availability of fuel-resistant Silastic fluoro liquid silicone rubber (F-LSR) provides additional options for your specific manufacturing and market needs

Enhance your products with built-in protection   Seal electrical systems   Manufacture mat seals and gaskets that: Withstand continuous high temperatures Electrically insulate and protect Reduce exposure to smoke and toxic fumes.   Learn More Add temperature resistance   Manufacture perimeter seals that: Maintain physical properties when exposed to continuous high temperatures Accommodate wide variations in temperature extremes   Learn More Specify the right elastomer For connector seal and gasket applications, we recommend either a high consistency rubber (HCR) elastomer or liquid silicone rubber (LSR) elastomer with a durometer between 18 and 70 Shore A.  These materials, available as either self-lubricating or non-self-lubricating, should be able to be easily molded in compression, transfer, or injection molding machines. Take advantage of our compounding expertise We know that your connector seal and gasket needs often include specifications which cannot be met with "off-the-shelf" materials. We can tailor or custom compound silicone elastomers to meet your exact connector seal and gasket requirements.
