Hi-Temp Shrink Tube 18mm (.70in) x 4ft

The Hi-Temp Shrink Tube 18mm (.70in) x 4ft from DESIGN ENGINEERING is an essential component for any serious mechanic or automotive enthusiast managing wiring harnesses, fuel lines, and sensor bundles in high-heat engine bays. This shrink tube is designed to protect electrical connections and fluid lines from abrasion, moisture, and thermal damage, making it critical for modified engines, turbo installations, or custom fuel system builds.

Constructed to withstand extreme temperatures, this heat-resistant tubing creates a tight, sealed barrier that resists fuel vapors, coolant splash, and oil mist. It shrinks uniformly when heated, ensuring a reliable fit that outperforms standard PVC wrap. The 18mm diameter and 4-foot length make it suitable for mid-sized wire bundles and sensor harnesses without adding excess bulk.

Ideal for engine builds and repairs, this shrink tube provides flexibility to protect multiple connection points or extended routing runs. Whether you're consolidating harnesses or sealing vulnerable connections near headers and exhaust manifolds, this product delivers the reliability needed in demanding automotive environments.
