Medium wall heat shrink tubes with mastic – type RPM

Medium wall heat shrink tubes with mastic – type RPM

Application: RPM tubes are on all length covered with mastic sealing. They are designed for the protection of metal pipes’ joints and other connections which require reliable sealing.
Radiation crosslinked covering guarantee effective mechanical protection. Mastic layer guard against moist and water penetration.

  • Operating temperature: from -35 up to +110°C (IEC 216)
  • Shrink ratio: 3:1
  • The minimum shrink temperature: +120°C
  • Standard color: black
  • UV resistant
  • Covered on all length with mastic sealing
  • Good insulation properties
