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.

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.

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.

Elongation and joint compression/expansion 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.

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

Sealants with low locking strength prevent threads from loosening due to vibration and can be adjusted without tools.

Sealants with medium locking strength prevent threads from loosening due to vibration and shock. They require a hand tool to unthread.

PTFE provides a slippery surface that keeps threads from binding. These sealants never fully harden, remaining pliable enough to self-heal and stop leaks before they start, so they’re often used in high-vibration applications that could cause standard thread sealants to fail. Since they have low locking strength, these sealants can be adjusted without tools.

VOC (volatile organic compounds) regulations restrict sales of sealants that cannot be sold to the listed jurisdictions/areas.

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.

Sealants with low locking strength prevent threads from loosening due to vibration and can be adjusted without tools.

Sealants with medium locking strength prevent threads from loosening due to vibration and shock. They require a hand tool to unthread.

To adhere to safety standards for drinking water systems, use sealants that meet NSF/ANSI 61.

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.

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. Sealants with medium locking strength prevent threads from loosening due to vibration and shock. They require a hand tool to unthread.

Sealants with high locking strength work in demanding applications, such as securing mounting studs in motor housings. They require both heat and a hand tool to unthread.
