Gaskets for Gasoline | McMaster-Carr

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. They cannot be sold to California because they exceed local regulatory limits on VOCs (volatile organic compounds).

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.

Self-Leveling Chemical-Resistant Sealants

Designed to withstand extreme environments, these fluoroelastomer sealants have excellent resistance to sulfuric acid, hydrochloric acid, nitric acid, gasoline, and oil. Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

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. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Sealants that cannot be sold to the regions listed exceed local regulatory limits on VOCs (volatile organic compounds).
