Measure the outer diameter of your handle or tube. Choose the size that is slightly larger than your handle diameter so the tubing slides on before shrinking. Φ45mm (≈1-3/4" flat width) generally fits handles in the 25–35mm diameter range, while Φ50mm (≈2" flat width) suits handles in the 30–40mm range. When in doubt, size up — you can always trim the ends after shrinking.

This tubing features a textured outer surface with a raised pattern that increases friction between your hand and the handle. Unlike smooth PVC heat shrink, the texture provides tactile grip even when hands are wet, oily, or gloved — making it well-suited for tool handles, fishing rods, bicycle handlebars, and similar grip applications.

This textured heat shrink grip tubing generally activates at temperatures between 70°C and 110°C (158°F–230°F). A heat gun set to low or medium is recommended. Move the heat gun steadily along the tubing from one end to the other to ensure even shrinkage. Avoid concentrating heat in one spot, which can cause uneven shrinking or surface distortion.

Yes. Once properly shrunk, this tubing generally provides moisture resistance suitable for outdoor use — including fishing rods, garden tools, and sports equipment handles. The textured surface maintains grip even when wet. It is not rated for prolonged submersion, but performs well in rain, humidity, and typical outdoor workshop environments.

This heat shrink grip tubing is compatible with most rigid handle materials including metal (steel, aluminum), fiberglass, carbon fiber, wood, and hard plastic tubes. It is commonly used on tool handles, fishing rod grips, bicycle handlebars, knife handles, walking sticks, and sports equipment. Ensure the handle surface is clean and dry before applying for best adhesion.

Each "root" is 1 meter (≈39.4 inches) of tubing. You can order 1, 2, or 3 roots per color and diameter combination. One meter is typically sufficient for a single tool handle or fishing rod grip section. For longer handles or multiple applications in one session, ordering 2–3 roots is recommended.

No — color is purely cosmetic and does not affect grip texture, shrink performance, or durability. All five colors (Black, Red, Green, Blue, Yellow) use the same textured PVC material and shrink ratio. Choose your color to match your tool, equipment, or to color-code handles by user or function in a workshop setting.
