Splice Technologies' "High Temperature" series Ribbon fusion splice protection sleeve is designed to work in elevated temperature environments. These fiber protection sleeves have been specifically developed for use in deep hole Oil and Gas industry applications where operating temperature resistance of 155°C is required. They also encompass outstanding abrasion and cut-through protection, high dielectric strength, and are highly resistant to most industrial fuels. Stock lengths are 30 and 40mm with a maximum after shrink diameter of 5.2mm. This product is constructed with an inner meltable nylon adhesive tube, glass strength member and a clear polyvinylidene flouride heat shrink outer tube. The entire assembly is clear to allow viewing of the fiber during and after splicing. We are proud to say that all of our products are made here in the USA, and most sleeves are in stock ready for immediate delivery.
