3/8" Shrink Tubing With Glue 4' 3:1 Ratio

The 3/8" Heat Shrink Tubing with Adhesive Glue Liner (4' length, 3:1 ratio) provides a waterproof seal for larger wire repairs and underground splice protection.
Overview The HSTUBE003-4 is a 4-foot length of 3/8" (9mm) dual-wall heat shrink tubing with a glue-filled inner liner. It is sized for larger conductors and multi-conductor cables where the 1/4" size would be too tight. When heated, the outer jacket shrinks at a 3:1 ratio while the adhesive liner melts and flows around the splice or wire, sealing out moisture. The adhesive glue liner creates a fully waterproof seal without separate sealant, making this tubing suitable for direct-burial splices, pump wire connections, and any outdoor or underground repair requiring long-term moisture protection. Sold in a 4-foot length; cut to desired piece lengths.
