Its flexibility allows it to expand up to 1.5 times its normal diameter, enabling easy installation over flanges, sensor threads, or larger exhaust pipes. The sleeve's pre-cut length of 12 inches is ideal for 4-inch diameter tubes, and it can be cut to custom lengths as needed. Finishing the installation is straightforward with included ties and a locking tie tool, ensuring a secure fit that maintains optimal performance and safety.

It exhibits resistance to abrasions, oil spills, temperature fluctuations, and vibration breakdown, contributing to long-lasting durability in harsh environments. Its unique construction promotes increased airflow, which can enhance exhaust performance and reduce heat transfer to vehicle cabins, protecting sensitive components. The sleeve’s pliable nature allows for a tight, secure wrap around complex shapes without requiring pre-wetting, simplifying installation.
Featuring a hi-tech carbon fiber look, the DEI Titanium Knit Sleeve combines functionality with a sleek appearance. It is suitable for various automotive applications, including wrapping exhaust components to reduce temperature and vibration-related issues. The product complies with Prop 65 standards and is not subject to air freight restrictions, making it a convenient choice for both professional installers and enthusiasts seeking reliable heat shielding solutions for their vehicles.
