About Sealant Flexibility
More
Self-Leveling Oil- and Fuel-Resistant Sealants
Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.
Elongation and joint expansion/compression tolerance indicate flexibility. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint expansion/compression tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.
Sealants that cannot be sold to California exceed local regulatory limits on VOC (volatile organic compounds).

Oil- and Fuel-Resistant Sealants
These non-sagging sealants will not drip while hardening on vertical and overhead surfaces. They’re thicker than most non-sagging sealants, so they can be used in vertical joints up to 1/2" wide.
Elongation indicates flexibility—the higher the values are, the more sealants can stretch. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
Silicone sealants have excellent ozone resistance.

Oil-Resistant Sealants
Make tough, flexible, oil-resistant seals. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, 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.

Structural Oil- and Fuel-Resistant Sealants
Impervious to the swelling effects of oils, fuels, and solvents, use this high-strength silicone sealant to assemble and repair fuel systems and tanks. Silicone forms a tough, rubbery, UV-resistant seal that remains flexible over time. It's non-sagging, so it won't drip from vertical and overhead surfaces. Also known as RTV (room-temperature vulcanizing).
Elongation and joint expansion/compression tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. This sealant is best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
