Big cable, big joint — you need insulation that covers the whole splice without a fight. This 20mm inner-diameter heatshrink tube slides over the connection, shrinks tight with a heatgun or hairdryer pass, and seals out moisture for good. Five metres per box. Stacks flat in your van tray so it's not buried when you need it mid-job. VW-1 flammability rated. RoHS and UL224 approved. Red colour-coding keeps polarity obvious on the panel
