Threadlockers

Prevent threaded fasteners from loosening due to shock and vibration. These threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked. 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.

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

087 is for coarse threads.

088 has a thin consistency to flow into fine threads.

262 fluoresces under UV light for easy inspection. It can bond slightly oily parts.

Heavy Duty Threadlockers

To withstand demanding, high-vibration applications such as motor and pump housings, these threadlockers have high breakaway torque. They begin to harden once coated surfaces are threaded together and exposure to air is blocked.

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.

263 bonds oily fasteners and does not require primer. Those that meet NSF/ANSI 61 are good for use with drinking water systems.

277 fluoresces under UV light for easy inspection. It works on lightly oily fasteners.

Quick-Set Threadlockers

These threadlockers develop usable strength within one hour. Because they harden quickly on most metals, they don't require a primer. They begin to harden once coated surfaces are threaded together and exposure to air is blocked.

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.

Noncorrosive Silicone Sealants

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, sealants are RTV (room-temperature vulcanizing).

Sealants that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).

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.
