This 1/2″ ID 2.5:1 semi-rigid adhesive-lined heat shrink tubing is engineered to seal and protect 84 AWG wire connections in harsh environments. The outer polyolefin layer is semi-rigid and flame-retardant for abrasion resistance, while the internal adhesive lining flows when heated to create a moisture-resistant bond over terminals and splices.
