Pair these sleeves with electrical-protection gloves for full arm coverage when working near equipment running at 17,000V AC or higher. Rated to ASTM D1051 standards for handling live electrical equipment, these sleeves come tested and marked with the test date. You have one year from the test date to put sleeves into service before they must be retested. Once in use, sleeves should be tested every six months. All have a colored inner layer that shows through as the coating wears down, helping you spot cracks, pinholes, and other signs of damage.

ASTM defines voltage classes for rubber insulating sleeves. Make sure the sleeves and gloves you use are rated for the voltage class of your equipment.
