Vibrant 3.5in I.D. x 4.250in I.D. x 4.5in Long 4 Ply Gloss Black Silicone Transition Hose

Vibrant Performance Aramid Reinforced Silicone Transition Hose Couplers feature High Temperature Resistant Aramid Reinforcement Fabric between each layer of silicone which allows for an impressive Operating Temperature Range of -75 Degrees F to 392 Degrees F (-60 Degrees C to 200 Degrees C). Suitable for Water, Coolant and Air service only.

The Vibrant VIB19748 Silicone Transition Hose Coupler provides a reliable connection between tubing sections with different inside diameters. Designed for automotive air, coolant, and water service, this 4-ply hose features a durable gloss black silicone construction suitable for demanding engine bay and performance applications. Its stepped transition profile helps simplify the connection of mismatched pipes while maintaining a secure, flexible seal when paired with compatible clamps and tubing.
The hose uses high-temperature-resistant aramid reinforcement fabric between each silicone layer for added strength and stability. This reinforced construction helps the coupler resist pressure, flexing, and repeated temperature changes during operation. The Vibrant transition hose is engineered for an operating temperature range from -75°F to 392°F, making it suitable for a wide variety of under-hood environments and custom plumbing installations.
The Vibrant VIB19748 is intended for water, coolant, and air service only. Its flexible silicone material supports easier installation and routing than rigid connectors, while the stepped design accommodates tubing with different diameters. Use this coupler for intercooler, intake, cooling, or general automotive plumbing projects where dependable temperature resistance and reinforced performance are required. Clamps are not included.
