Silicone coated fiberglass braided wire protection sleeve is used for insulation of leads and connections in electrical and electronic components ( transformers, coils, relays, solenoids etc.) where temperature range from –70°C through 200°C are encountered. Our sleeves are UL/NEMA Thermal Class H and CSA rated. Our A grade tightly braided fiberglass sleeve completely coated with silicone resin provider superior electrical and thermal protection which makes them a high quality equivalent to Ben-Har 1151-XL200A, Varflo sleeving, Hilec Turbo 117F, Hilec Vol-Sil Grade A, Alpha Wire PIF-200. Silicone rubber coated glass sleeving is the only flexible insulating material which remains useful for continuous service in ambient temperatures from -70°C through +200°C as the coating maintains its electrical integrity even under severe fire conditions by forming a non-conductive ash.
