What material are the inter-panel links of the Spring panel for pool heating (SP) made of?
The inter-panel connection of the Spring in swimming pool (SP) is a flexible PVC hose reinforced by a rigid PVC rod with interior x exterior diameter: 26mm x 32mm. A shockproof white ring is embedded in a spiral inside a soft black PVC core (temperature range: 15-50°C).
NB: SP connections are compatible with glycol if a pressurized pool installation is used. However keep in mind that they are not suitable for temperatures above 60°C.
