DHEC - End Cap/Water Stop
Colors: Black
Adhesives: Adhesive: Mastic Strips
Category: Heat Shrinkable Pipeline Coatings
Covalence DHEC is a heat shrinkable, tubular end cap primarily used for preventing the ingress of water between the casing and insulated service pipe. It is a molded part with different espansion ratios in each end to accomodate the diameters on both casing and service pipe.
  • DHEC Single is designed for pre-insulated pipes having one service pipe.
  • DHEC Twin has two outlets and is designed for pre-insulated pipes with two service pipes.
  • The elastomeric adhesive is specially designed for high temperature performance.
  • The uncoated edges prevent the sleeve from slipping off the casing pipe during installation.


  • DHEC is used for pre-insulated pipes carrying fluids at continuous operating temperatures of up to 130°C (266°F).
  • It is a perfect end seal for all house connections and man holes, protecting the integrity of the thermal insulation.
