RJS-E
Wrap‑around heat‑shrink sleeve for sealing the joint casings of pre‑insulated district heating pipes. A cross‑linked HDPE backing (PE‑X) and a dual adhesive: a high‑shear hot‑melt at the edges anchors the sleeve against ground movement, and a visco‑elastic sealant in the centre forms the actual moisture seal. A dimpled Permanent Change Indicator on the backing disappears once the correct shrink temperature is reached, so a finished joint can be inspected afterwards.
The edges anchor, the centre seals.
The drawing is Kampek's own. It asserts only what is already published on this site or on the manufacturer's own pages.
