Kingflex rubber foam insulation tube

Kingflex rubber foam insulation tube has better heat-preservation effectiveness than PE material. Because of its best heat insulation property, they are widely used in chilled-water pipes, water pipes, air ducts of family air-conditioner, house-use fission air-conditioning and its joint pipes; side board, cover and bottom board and back board; hot-water pipes of building inner fitment, etc.
  • nominal wall thicknesses of 1/4”, 3/8″, 1/2″, 3/4″,1″, 1-1/4”, 1-1/2″ and 2” (6, 9, 13, 19, 25 , 32, 40 and 50mm)
  • Standard Length with 6ft (1.83m) or 6.2ft(2m).
