PVC Heat Shrink Tubing — Large-Diameter Wrap Sleeving for Cables, Pipes & Bundles
Whether you're insulating a thick wire harness, protecting a copper pipe joint, color-coding industrial conduit, or bundling garden hoses, finding PVC heat shrink tubing in the right large diameter is rarely straightforward. This range of PVC heat shrink tubing covers flattened widths from 103mm (≈4.1") all the way up to 625mm (≈24.6"), giving electricians, plumbers, fabricators, and serious DIYers a single source for sizes that most hardware stores simply don't stock.
Each piece is sold as a 1-meter (≈39.4") length of lay-flat PVC heat shrink sleeving. The flattened width listed in each variant corresponds to a specific inner diameter (φ) — for example, 103mm flat = φ65mm (≈2.6") inner, and 500mm flat = φ318mm (≈12.5") inner. Colors available include Black, White, Blue, Clear, Red, Green, Grass Green, Fruit Green, Yellow, Silver Grey, and thickened variants (Blue Thickened, Clear Thickened) for added wall strength. Simply slide the tubing over your object and apply heat with a heat gun to achieve a snug, protective wrap.
Typical use cases include insulating and protecting large cable bundles and wire looms, wrapping copper or PVC pipe joints for moisture resistance, color-coding conduit runs in electrical panels and industrial settings, and providing a clean cosmetic sleeve over handles, grips, or structural tubing in fabrication projects.
