Professional grade military spec flexible polyolefin tubing provides excellent electrical insulation, protection from dirt, dust, solvents, and foreign materials as well as providing strain relief. Over expanded tubing easily fits over the end of wires and connectors and shrinks down to 33% of it's original diameter for a snug water-tight protective seal without a reduction in the tube's original length.

Protect expensive spark plug wire sets from potential burning, cracking, and hardening typically caused by severe under hood heat. Easily installs on wire by removing distributor boot and sliding Protect-A-Wire(TM) over spark plug wire. Buy in bulk with these 50 foot rolls of Protect-A-Wire. Great for shop use so Protect-A-Wire(TM) is always in stock.

Protect-A-Boot Ringless Sleeves are superior protection for extreme angled plug wire boots that solve the problem of burning and cracking plug boots and wires from header and engine heat. DEI Protect-A-Boot Ringless Sleeves are uniquely designed to protect spark plug boots & wires against the harmful effects of direct and continuous heat - up to 1200F. Continued exposure to extreme heat generated from the engine block, exhaust manifold and headers can cause burn through, hardening or cracking of the spark plug wires and boots.
