Duraseal TE Connectivity Raychem splice
Duraseal products insulate and protect electrical connections against various forms of wear, including mechanical wear, but also the sudden pulling out of wires, which can cause an electrical connection to be broken. In addition, the products from the DuraSeal series have the property of protecting connections against moisture, salt and other types of grime.
The product range for the duraseal are characterized by offering protection to connections in the most severe environmental conditions. The crimp connection is encased in a rugged, heat-shrinkable nylon hose lined with a special hot melt adhesive that protects against damage from abrasion and cuts.
DuraSeal products remain flexible and provide long-lasting protection where comparable products would have become brittle. The wide range of DuraSeal products consists of products for various wire sizes.
