Oil-Resistant Sealants
| | |
Cartridge | Tube | Nozzle-Top Can |
Make tough, flexible, oil-resistant seals. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone rubber, sealants are RTV (room-temperature vulcanizing). Note: These sealants are not for use on parts that come into contact with gasoline.
Elongation and joint expansion/compression tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
