Also known as thumb-grade caulk, this forms a non-hardening, moisture-resistant seal that remains pliable.

Made from silicone, these sealants are RTV (room-temperature vulcanizing).

Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete.

A combination of hardness and surface tension makes these sealants resistant to punctures, cuts, and abrasion.

Apply these sealants in cold temperatures, on wet surfaces, and even through running water.

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

These sealants are marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light.

Thinner than non-sag sealants, these flow easily into cracks and have a smooth finish.

Seal joints and gaps in concrete.

These sealants come in bottles, cans, and tubes so you can choose the quantity that covers your application.

Seal metal-to-metal joints in ductwork.

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.

Formulated for high lubricity, these sealants allow easy assembly of finely threaded hydraulic and compressed air system components. They're also free of fillers that could contaminate system media.

Prepare joints and surfaces to ensure proper sealant adhesion.
