OBO BETTERMANN Rehau RAUDUO Coupling 40/105 RAL9010 RD Kup40105 rws (6132176)

In pre-insulated pipe systems for district heating, creating a durable, watertight joint between service pipe and casing is critical. The OBO BETTERMANN Rehau RAUDUO Coupling 40/105 solves this by providing a heat-shrinkable connection that seals the casing pipe to the service pipe, ensuring long-term integrity of the insulation. This coupling is specifically designed for Rehau RAUDUO systems with a 40 mm service pipe and 105 mm casing pipe, in RAL 9010 pure white.

Who is it for

Installers and contractors working on pre-insulated pipe networks, especially district heating and cooling systems, who need a reliable, watertight joint that withstands environmental stress. It is ideal for both new installations and repairs on Rehau RAUDUO pipes.
