Key specifications

Choosing the right option

For a cartridge-dispensed RTV with a bead-width nozzle see CRC RTV Silicone Select-A-Bead Sealant; the two products have different data sheets and their temperature figures should not be treated as equal. To remove old gasket material first see CRC Aerosol Gasket Stripper Safe On Aluminium, Steel & Brass 300g.
