QES 4:1 tubing has an outer jacket of flame retarded, radiation cross linked, semi rigid polyolefin. The inner layer is comprised
of a hot melt adhesive designed to adhere to all major electrical cable insulations and components. The inner layer also
performs well at an extended temperature range.
Overall the QES 4:1 is a new, low cost solution to providing protection against moisture, flexing, abrasion and cut throughs
of electrical splices and components.
