Specifications
The tubing must be usable both indoors and outdoors, in overhead, direct-buried, or
submerged applications on cables rated up to 1000 volts. It is not adversely affected by
moisture, mild acids and alkalies, fuels, oils, ozone, or ultraviolet light. It must be compatible
with and adhere to all types of cable jackets, including rubber, plastic, or lead. It must
conform to the requirements of UL 486 D and sections 3.4 and 4.3 of ANSI C119.1 1986.
