Loctite 243 Primerless, Oil Tolerant, Removable Medium Strength Blue Threadlocker

Top Pick Loctite® 243™ Primerless Threadlocker is an oil tolerant, removable, medium strength, blue threadlocker designed for the locking and sealing of threaded fasteners between 1/4" and 3/4" (6 to 20 mm). It not only works on active metals (e.g. brass, copper) but also on passive substrates such as stainless steel and plated surfaces. It tolerates minor surface contaminations from various oils, such as cutting, lubrication, anti-corrosion and protection fluids.

Loctite 243 is the recommended replacement for Loctite 2440™.

 

This "Next Generation" threadlocker provides:

  • Upgraded temperature resistance - up to 360°F
  • Oil tolerant curing on as-received fasteners without cleaning
  • Primerless performance on both inactive and active metals
