HPS Performance Products HTSR-400-550-L6-BLUE Silicone Reducer Hose 4" to 5-1/2" ID 6" Long Blue 4-Ply High Temp

The HPS Performance Products HTSR-400-550-L6-BLUE is a high-temperature, 4-ply reinforced silicone reducer hose designed to transition between 4-inch and 5-1/2-inch (5.5") inner diameters over a 6-inch length. Available in a bold blue finish, this reducer hose is an essential component for custom turbocharger piping, intercooler plumbing, cold air intake fabrication, and radiator cooling system builds. Its flexible reducer design allows clean, leak-free connections between mismatched pipe diameters in both professional and DIY installations.

Key Features:

• 4-ply reinforced silicone construction for superior burst strength and long-term durability under pressure
• High-temperature rated — meets and exceeds SAE J20 industry standards for heavy-duty pressure connections
• Transitions 4" to 5-1/2" inner diameter over a 6" hose length — ideal for connecting mismatched intercooler or intake pipes
• UV and ozone resistant — maintains flexibility and integrity in harsh underhood and outdoor environments
• Excellent resistance to heat, pressure, and vibration
• Well-suited for marine, automotive, and industrial applications including turbo systems, intercooler piping, and radiator cooling circuits
• Not compatible with fuel or oil — for air, coolant, and water transfer applications only

HPS Performance silicone hoses are engineered for enthusiasts and professionals who demand reliable, high-performance connections. The vibrant blue exterior provides a clean, finished look in custom engine bays. Clamps are not included and must be sourced separately to match hose diameter.
