Standard hose for almost all applications. Available in different dimensions. Beautifully transparent and flexible, so the hose is easy to lay. Suitable for UV active or coloured water additives. We recommend the use with 13mm hose connectors to achieve an optimal HighFlow effect. Inner diameter 12mm outer diameter 16mm Price per 1 meter Not suitable for plug-in connections (push-in or P&C) but only for grommets with over-nut or hose connections (e.g. with hose clamp) Please note: Transport and storage conditions may cause the hose to arrive at the customer’s premises somewhat “undercooled”. Cold PVC hose tends to get a little hard. For optimal installation, we therefore recommend that the hose is either stored in a warm room for a few hours after receipt before installation, or briefly placed in hot (e.g. 60°) water. Then the hose will have reached its optimum bendability.
