Loctite 545 Thread Sealant


Loctite 545 Thread Sealant

Loctite 545 is a pipe thread sealant designed for locking and sealing of metal pipes and fittings. It is specially formulated to offer high lubricity for easy assembly and removal. Recommended for fine threaded fittings as used in hydraulic and pneumatic installations and small fittings in general.


  • Prevents leakage: It fills all gaps between the mating threads and cures into a hard thermoset plastic that provides 100% seal.
  • Does not clog downstream filters in hydraulic and pneumatic systems as unused adhesive gets washed away.
  • Easy to disassemble with standard hand tools as medium strength product.
  • Seals pipe joint against corrosion.
