E-Z Bead ~ Supreme Sealant

E-Z Bead Supreme


Castle® E-Z Bead™ is dispensed through a pressurized can for a clean, smooth, continuous bead of any size. E-Z Bead’s RTV Silicone™ makes a permanent flexible seal for a multitude of uses. Special formulations are designed for specific applications. E-Z Bead’s™ Innovative applicator allows easy application of RTV Silicone to any surface even when applying to overhead or vertical surfaces. It eliminates package waste of product due to poor closure of traditional squeeze tubes of caulking guns that become hard after one use. Castle® E-Z Bead Supreme™ is the ultimate gasket maker in our Hi- Temp power pack. Supreme represents the most advanced technology in RTV silicone today. E-Z Bead Supreme™ RTV silicone is high temperature, low odor, low volatile, non-corrosive, resistant to hot oil and glycol. It has superior, non-leak characteristics. E-Z Bead Supreme™ will withstand temperatures form -85°F to 550°F. Supreme will not affect oxygen sensors.
