DEI’s professional‑grade electrical tubing is constructed from military‑spec flexible polyolefin, delivering robust insulation and protection against dirt, dust, solvents, and foreign materials while providing reliable strain relief. The over‑expanding design shrinks to 33 % of its original diameter, creating a snug, water‑tight seal without shortening the tube’s length. With a 3:1 shrink ratio, the tubing is ideal for insulating wires, connections, terminals, and wire splices in demanding environments.
The tubing operates across a wide temperature range of –67 °F to 275 °F and is applied at 120 °F to 180 °F using a heat gun. Manufactured in the United States, it meets the stringent requirements of professional electrical applications.
