Gastite® P2 offers the flexibility and key features of our original CSST, with the added benefit of an integrated containment sleeve in UV resistant polyethylene.

Developed as a solution for unvented voids, the external jacket has a ridged underside, which creates space between the outer jacket and the inner pipe, allowing for gas to ventilate should it need to.

Key features of Gastite® P2

  • No need for additional sleeving when installing in unvented voids.
  • Heat annealed for flexibility.
  • Pre-marked by the metre.
  • Compatible with XR2 fittings which eliminate exposed steel beyond the nut.
  • No hot works for safer installations.
  • 75% fewer fittings, when compared to traditional piping methods, meaning a safer system with less leak potential and reduced call backs.
  • Suitable for internal and external burial in accordance with manufacturer’s instructions.
  • Connect directly to the meter box and appliance.
  • Suitable for all modes of construction, including residential, commercial, new build and industrial.
