Splice Technologies, Inc.' "High Temperature Dielectric" series single fiber fusion splice protection sleeve is designed to work in elevated temperature environments, and where non-conductive materials are required. 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 40 and 60mm with an after shrink diameter of 2.6mm and will accommodate fiber diameters up to 1.4mm. This product is constructed with an inner meltable nylon adhesive tube, clear quartz 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.
