HP Builder’s Kits feature a heat protective thermal sleeving capable of withstanding 1200°F continuous. This non flammable sleeve has a special weave that allows it to expand and contract over fittings. These sleeves can protect fuel lines, preventing vapor lock. They can also be used to protect wires from heat damage and allow you to hide your wiring. The 5/8” id sleeves are ideal from protecting your oil lines from heat damage caused by being too close to the motor or exhaust. So add some heat protection and make your ride a cooler one.
