I've been using Nelco Products for various tyrap and heat shrink tubing requirements for the past year and have found them -- and especially Bill -- to be very helpful, knowledgeable and responsive when I have a special requirement or urgent delivery need. I'm so glad I cam upon Nelco Products through an online search after a long-time supplier had yet again raised prices and was VERY unresponsive to special requests. Way to go Nelco!!
EMI Shielded Heat Shrink Tubing provides a convenient method of adding secondary insulation and EMI shield protection to in-service electrical systems. It is ideal for cables diameters of 1/2" and less. The tubing is MIL-I-23053/5 combined with a conductive cloth shield which has excellent shielding properties.
