4 Ply Silicone Sleeve 3in I.D. X 36In Long

The 4 Ply Silicone Sleeve 3in I.D. X 36In Long from Vibrant Performance is an essential reinforced hose component designed for high-performance automotive cooling, intercooler, and boost applications. This precision-engineered sleeve accommodates demanding engine modifications where standard rubber hose fails to withstand pressure cycling, temperature extremes, and chemical exposure. Whether you're building a turbocharged street engine, upgrading intercooler plumbing, or assembling a custom cooling circuit, this 36-inch silicone sleeve provides the durability and reliability that serious enthusiasts and professional mechanics demand.

Constructed with four reinforced plies of premium silicone, this hose sleeve delivers superior burst resistance and long-term flex fatigue life compared to standard single or dual-ply alternatives. The 3-inch inner diameter accommodates substantial coolant or boost airflow while the four-ply construction maintains structural integrity under sustained pressure and thermal cycling—critical when ambient temperatures swings from winter cold starts to summer heat soak scenarios. Silicone's inherent chemical resistance protects against coolant additives, oil contamination, and automotive fluids that degrade conventional rubber hoses, ensuring consistent performance over thousands of operating hours.

Mechanics and engine builders working on turbocharged applications, LS conversions, and custom cooling systems consistently choose Vibrant Performance silicone sleeves for their proven track record in both street and competition environments. The 36-inch length accommodates flexible routing through tight engine bays while the 3-inch bore handles high-volume coolant or intercooler discharge lines without flow restriction. Installation pairs seamlessly with hose clamps and barbed fittings—measure your plumbing needs carefully and verify fitment against your specific hose routing before ordering to ensure optimal system integration.
