Silicone Sealants

Made from silicone, these sealants are RTV (room-temperature vulcanizing). They’re non-sagging, so they won't drip from vertical and overhead surfaces.
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.
When Dow Corning 700 requires a primer, for best results use PR-1200 on metal and PR-1205 on plastic.

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. 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.

Non-Hardening Thread Sealants

Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start. They have low locking strength, so they can be adjusted without tools.
To adhere to safety standards for drinking water systems, use sealants that meet NSF/ANSI 61.
Sealants that cannot be sold to the listed regions are restricted due to local VOC (Volatile Organic Compounds) regulations.
