Titanium Protect-A-Sleev 1/2in x 4ft.

The Titanium Protect-A-Sleev 1/2in x 4ft. from Design Engineering is a heat and abrasion protection sleeve designed for engine builders, performance mechanics, and motorsport enthusiasts who require durability in high-temperature environments. This sleeve is essential for routing fuel lines, brake lines, or wiring harnesses near exhaust manifolds, headers, or turbochargers, providing protection against radiant heat, spark damage, and mechanical wear.

Constructed from titanium-coated fiberglass material, the Protect-A-Sleev is engineered to withstand extreme under-hood temperatures without degradation. Its flexible design allows for easy installation in tight engine bays, while the 1/2-inch inner diameter accommodates most fuel, coolant, and brake line sizes. The 4-foot length offers ample coverage for both single and multiple component installations.

This sleeve is particularly beneficial for those upgrading to high-output turbocharged, supercharged, or naturally aspirated engines, where managing underhood heat is critical for longevity. Custom builders, drag racers, road-course competitors, and street enthusiasts will find this product invaluable for maintaining reliability and safety in their vehicles.
