Upgrade your cooling system with our radiator overflow PVC tube, designed to fit radiators with an 8 mm OD overflow pipe. Manufactured from flexible, high-quality PVC, this tube is built for durability and reliable service across automotive, motorcycle and general equipment cooling / overflow applications. This figure is based on the theoretical burst pressure at 20°C, using a safety factor 4:1. Any increase in temperature above 20°C will result in a decrease in pressure capabilities. Efficient cooling support: Helps manage coolant overflow and reduce mess, supporting stable operating temperature For best results, ensure the tube is fully seated on the overflow outlet and routed away from sharp edges and hot components. Clamp if required for your application. Experience peace of mind.
