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-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.

Titanium Protect-A-Boots(TM) XL are the latest in thermal protection technology for spark plug boot protectors. Developed from a unique material mined from lava rock stranded and woven into a proprietary weave for added durability and strength yet is pliable enough to provide a universal fit for straight or angled boots. Titanium Protect-A-Boots XL are naturally resistant to heat, chemicals, abrasions and contaminants, and are engineered to withstand temperatures up to 1800F (983C) of direct heat. High horsepower engine compartments are known for extreme heat that can put spark plug boots and wires at risk.
