LOCTITE® 565

Features and Benefits

This low-strength, high-viscosity thread sealant is UL classified to prevent loosening and leakage from vibration also in devices handling gasoline, petroleum oils, and natural gas.
LOCTITE® 565 is a white, 1-part pipe sealant that provides instant seal for air pressure testing. It is designed for locking and sealing tapered metal pipe threads and fittings. It cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. It is resistant to most industrial fluids, and withstands continuous temperatures to 300°F (150°C), intermittent to 375°F (190°C). It has controlled torque strength for easy disassembly, and is low odor.
  • NSF/ANSI 61 certified
  • 1-part: no mixing
