Shield your wiring, lines, hoses, and from engine room heat. Thermaflect Sleeve acts as a thermal barrier capable of reflecting up to 90% of radiant heat away (requires minimum of 1 inch of airspace and good airflow). It weighs a fraction of what silicone coated sleeves do and it offers superior radiant high heat wire insulation. Thermaflect Sleeve withstands 1100°F of continuous radiant heat and 500°F direct heat. Also available in a hook and loop seam.

The following conversion is a guide for AN hoses only. The conversion reflects the most common conversions for AN hose sizes, however there may be some variances with different manufacturer's. Always double check by measuring the OD of your hose. Always verify the OD of your hose, you may use a caliper or sliding an open end wrench over the hose. If you are still unsure verify with the manufacturer of the hose as to their specific OD. By using this calculator you acknowledge this is a guide only and it is ultimately your responsibility to verify the correct OD of your AN line.
