Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone rubber, sealants are RTV (room-temperature vulcanizing).

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.

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.

These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. 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. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.

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. These sealants are anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air.

Seal concrete joints in high-traffic locations—these sealants stand up to heavy wear and tear, such as steel wheel traffic. Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

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.

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 without PTFE, these sealants are less slippery and less likely to result in overtightenting than sealants that have PTFE, making them good for plastic pipe where overtightening could lead to cracks and breaks. They have low locking strength, so they can be adjusted without tools.

PTFE provides a slippery surface that keeps threads from binding. These sealants are anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air.

These sealants have high locking strength, so they work in demanding applications, such as securing mounting studs in motor housings. They also withstand applications with large temperature swings.

Apply this thread sealant stick without a mess. It contains PTFE, which provides a slippery surface that keeps threads from binding. Since the sealant is anaerobic, it doesn’t begin to harden until coated surfaces are threaded together, blocking exposure to air. It has low locking strength, so it prevents threads from loosening due to vibration and can be adjusted without tools. It meets NSF/ANSI 61 for use with drinking water.
