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. These sealants have medium locking strength, which prevents threads from loosening due to vibration and shock. They require a hand tool to unthread.

Adjustable Threadlockers

These threadlockers give a secure hold, but can be easily adjusted with hand tools. They can be removed without damaging countersunk fasteners, set screws, and other small fasteners. 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.
