Nate recommends 3:1 dual-wall, adhesive-lined heat shrink for marine electrical connections to provide strain relief and a watertight seal.0:31 The 3:1 ratio indicates the tubing shrinks to one-third of its original diameter, while the inner adhesive layer melts during heating to prevent corrosion.1:05 When selecting a size, choose tubing that fits over the terminal barrel but remains small enough to shrink tightly against the wire insulation.1:34 To apply, position the tubing over the connection and use a heat gun while rotating the wire to ensure even shrinking.2:32 Stop heating once the adhesive begins to extrude from the ends of the tubing.2:55 Avoid using an open flame, as it often leaves soot and risks burning or splitting the material.3:18 For off-grid installations without AC power, use a battery-powered heat gun instead of a flame to achieve a clean, professional finish.3:37 Proper heat shrinking protects the connection between the wire insulation and the lug.2:15
