Description
Varflo Sleeving is braided fiberglass coated with a modified polyvinyl chloride resin. Superior plasticizers, along with the best flame retardants and fungicides, make Varflo an outstanding Class 130°C sleeving. It has good flexibility and resistance to oils, solvents and moisture. Varflo has good shelf life and will not lose dielectric strength when subjected to severe twisting.
Specifications
Varflo Sleeving conforms to, and is listed on the Qualified Products List (QPL) for, MIL-l-3190/2, latest revision (Grade A); NEMA TF-1, Type 3; and ASTM-D372.
Under the Component Program of Underwriters Laboratories, Grade A Varflo Sleeving is recognized for 105°C, 600 volt service and complies with VW-1 flammability requirements under UL File #E63450. (VW-1 compliance of Grades B through C-1 is covered under UL File #E53690.) CSA International certifies the use of Grade A for 105°C, 600 volt service and flammability requirements under CSA File #LR58486 VW-1/FT1. Varflo is incorporated in systems work, per UL Standard 1446, to facilitate product acceptance by UL.
Applications
Varflo Sleeving is used to insulate leads in motors, transformers, generators and similar apparatus. Because of its excellent flexibility, good electrical properties and resistance to soldering temperatures, Varflo is also used in radio and TV as well as other electronic circuitry in measuring instruments, computers, etc. Varflo is used on both original equipment and aftermarket automotive industry applications such as regulators, starters, alternators, etc. primarily because of its toughness, flexibility and dielectric strength.
Sizes
AWG #24 through 2” l.D. Other sizes subject to inquiry.
Standard Color
Yellow and black. Other colors made to order.
Standard Packaging
Coils, spools or 36” lengths at manufacturer’s option, unless otherwise specified. There is no cutting charge for 36” lengths, but lengths other than 36” are subject to cutting charges. Sizes over 1” l.D. are generally supplied in 36” lengths.
