DualSeal RJS-E - Joint Seal for Insulated Pipe
Colors: Black
Backing Binder: HDPE
Category: Heat Shrinkable Pipeline Coatings
DualSeal RJS-E is a heat-shrinkable, wraparound sleeve for pre-insulated pipe joint sealing applications. It consists of:
  • A visco-elastic sealant in the middle acts as a primary moisture seal
  • A high shear-strength, thermoplastic adhesive at each side of the sleeve provides mechanical anchoring and acts as an additional seal.
  • A radiation crosslinked HDPE backing.

DualSeal RJS-E is available in 3 product constructions : /A, /B and /C, see product datasheet for details.
DualSeal RJS-E fully meets the EN489 (edition 2009) requirements and is certifed by FFI.


  • Endseal of heat shrinkable casings (cross-linked and non-cross-linked).
  • Endseal of oversized casing.
