Standard hose for almost all applications. Available in various sizes. Nice and transparent, and flexible, making it easy to lay the hose. Suitable for UV-active or colored water additives. We recommend using it with 13 mm hose connections to achieve optimal high-flow performance. Inner diameter 12 mm, outer diameter 16 mm, price per 1 meter. Not suitable for push-fit connections (Push-In or P&C), but only for fittings with a nut or hose connections (e.g., with a hose clamp). Please note: Due to transport and storage conditions, the hose may arrive somewhat "chilled" at the customer's location. Cold PVC hose tends to become a bit stiff. To enable optimal laying, we recommend storing the hose in a warm room for a few hours after receipt or briefly placing it in hot (e.g., 60°) water. This will allow the hose to achieve its optimal flexibility.
