Description
CRC RTV Silicone Sealant is a Room Temperature Vulcanizing all-purpose formula designed for a genuinely wide range of sealing, bonding, protecting and waterproofing applications, formulated specifically as a heavy-duty industrial gasket sealant rather than a general household product. Its RTV chemistry means it cures at ambient room temperature without needing heat or a separate catalyst step, making it a straightforward, safe option for sealing and bonding work directly in a workshop or on site.
It’s genuinely effective across HVAC, electrical, construction and metal working applications, and is well suited to filling gaps between mating parts, gearboxes, pumps and motors, as well as general gasket sealing work. That breadth makes it a practical all-rounder for a workshop dealing with mixed mechanical and electrical sealing tasks rather than needing a different sealant for each job type.
Application is genuinely refined for real-world control: the ‘Select-a-Bead’ nozzle allows easy adjustment of the silicone bead width to suit the specific gap or gasket being sealed, while a unique double piston pressurised system keeps dispensing smooth and uniform from the first squeeze to the last. Available in red, black and grey, it can be colour-matched to common gasket and sealant conventions across different equipment types. Note that this is an order-in product from CRC.
Because it cures at ambient temperature without a separate heat step, it’s a genuinely low-fuss option for on-site gasket and sealing repairs where setting up dedicated curing equipment isn’t practical. Keeping a tube on hand in the workshop means a genuine RTV repair can be made the moment a gasket or seal fails, rather than waiting on a replacement part or a specialist sealant order.
