NS7 - Cold Shrink Silicone Rubber Sleeve for Handle

-40~+200 Uvproof Rainproof RoHS


Using high weather resistance Silicone rubber sleeve expanded and assembled onto a spiral type removable plastic supporting core. Suitable applied to various handles of fishing rods, rackets, paddles, athletic equipment and industrial hand tools.
Replace the traditional way of EVA foaming and PU wrapping tape to avoid the possibility of loosening. Remove the supporting core at position that requires insulation and seal protection, the organic silicone rubber sleeve will quick and tightly shrink onto the handles. Allows to quick accomplishing the seal protection without using open fire and tools.
NS7 has an outstanding elasticity and texture, the grain on surface can increase the friction to achieve the anti-slip performance. The high-efficiency insulating material can enhance the safety of outdoor user to prevent accidently electric shock.
