Flexible PlafoTube® connection and coupling hoses with PK press fittings are the most important link between the individual heating and cooling elements. Their pressure resistance and oxygen diffusion tightness in accordance with DIN 4726 ensure long-lasting functionality, while the press technology creates a secure, non-detachable connection – ideal for flexible integration into non-serviceable, seamless ceilings. The hose impresses with its durability and flexibility.
