Permabond LH050P Pure Anaerobic Threadsealant
Categories: Polymer; Adhesive; Thermoset

Material Notes: PERMABOND® LH050 PURE anaerobic pipe sealant is single component paste that cures only when in contact with metal parts and oxygen is excluded. The sealant fills up the entire space between male and female parts, instantly sealing the connection for water, hydraulic fluids, air, gases and chemicals. Once cured, the cured anaerobic sealant typically exceeds the burst rating of the pipe and in addition it locks the pipes, plugs or fittings against vibration loosening. After cure, disassembly of fittings for maintenance is still possible using normal tools.

Permabond® LH050 PURE pipe sealant performs well on most metals, particularly steel and brass. It provides an excellent alternative to pipe dopes and pipe tapes for sealing pipe joints.

Another feature of PERMABOND® LH050 PURE is the ability to seal pipes that have not been fully seated. In piping systems, pipe joints must connect with other pipes and in the direction in which the joint must face may not allow the pipe to be fully seated. LH050 PURE will seal – even when the direction in which the pipe must face does not allow the complete seating of the threads. Anaerobic sealant will seal with simple hand assembly while still obtaining the seal of a fully torqued pipe joint.

Features & Benefits:

  • Full cure seal to the burst rating of pipe
  • Easy to use and apply
  • Directional freedom
  • NSF/ANSI 61 Certified - Drinking Water System Components
  • Does not contain solvents
  • Excellent chemical and temperature resistance
  • Cures at room temperature
  • Will not shred, tear or cause blockages
