Permabond MH052

Permabond® MH052 is ideal for the sealing of threaded joints. It is approved for use with natural gas and LPG for working pressure up to 20 bar (290 psi) and also for gaseous oxygen up to 10 bar (145 psi) and 60°C (140°F). MH052 seals against gas, water, LPG, hydrocarbons, oils and other chemicals and will seal to the burst rating of the pipe. Unlike PTFE tape or hemp, Permabond MH052 will not shred or dry out, so it will provide a durable seal, helping to extend the life of the components.

Features & Benefits

  • Excellent chemical resistance 
  • Pressure seal to burst rating of pipe 
  • No loose particles to clog valves 
  • Approved for use with gaseous oxygen 
  • WRAS listed for contact with wholesome (potable) water 
  • DVGW & BAM approval

Typical Curing Properties:

Maximum gap fill
Maximum thread size
0.5 mm 0.02 in
M56
2 in
Time taken to reach handling strength (M10 steel) @23°C 15 minutes*
Time taken to reach working strength (M10 steel) @23°C 1-3 hours
Full strength (M10 steel) @23°C

24 hours

*Handling time at 23°C / 73°F. Copper and its alloys will make the adhesive cure more quickly, while oxidised or passivated surfaces (like stainless steel) will reduce cure speed. To reduce curing time, use Permabond activator A905 or ASC10 alternatively, increasing the curing temperature will reduce curing time
