About Sealant Flexibility

About Structural Adhesives

Fill gaps up to 0.01" to secure unthreaded cylindrical metal parts such as shafts, bearings, and press-fit assemblies. These retaining compounds begin to harden once coated surfaces are pressed together, blocking exposure to air.

Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes, and cadmium and zinc coatings.

Retaining Compounds for Oily Close-Fitting Parts

Even on oily surfaces, these retaining compounds keep their hold. Use them to fill gaps up to 0.015" to secure worn cylindrical metal parts such as shafts, bearings, and press-fit assemblies. These retaining compounds begin to harden once coated surfaces are pressed together, blocking exposure to air.

Compounds with high locking strength require both heat and a hand tool to unthread.

Thread Sealants

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.

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.

Sealants that cannot be sold to the listed regions are restricted due to local VOC (Volatile Organic Compounds) regulations.

Drip-Free Thread Sealants with PTFE

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.

Thread Sealants for Hydraulic and Compressed Air Systems

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.

Thread Sealants for Refrigeration Systems

For use in refrigeration systems and applications exposed to strong chemicals, these sealants have excellent solvent resistance. They’re anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air. Sealants have medium locking strength, which prevents threads from loosening due to vibration and shock. They require a hand tool to unthread.

Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ACTIVITY after your order ships.
