Heat Shrink Shroud
Gala Heat Shrink Shrouds (GHSS) provides a watertight and fume-tight seal where cables enters inside the Glands. The Heat Shrinkable Shrouds are internally coated with hot melt adhesive for complete environmental protection from Moisture, Dust and Water, according to IP 68 (Ingress Protection). These shrouds are manufactured from high quality cross-linked polyolefin material.
