HPS Performance Products HTSR-112-125-BLK Silicone Reducer Hose 1-1/8" to 1-1/4" ID Black

The HPS Performance Products HTSR-112-125-BLK is a high-temperature reinforced silicone reducer hose designed to connect two different diameter hose or pipe ends. Transitioning from a 1-1/8" (28.6mm) inner diameter to a 1-1/4" (31.8mm) inner diameter over a 3-inch length, this reducer coupler is an essential component for custom turbo systems, intercooler piping, intake fabrication, radiator cooling circuits, and marine or industrial plumbing applications.

Key Features:

• Transitions from 1-1/8" ID to 1-1/4" ID — ideal for connecting mismatched pipe or tubing diameters
• 3" overall length for secure fitment and clamp placement on both ends
• Constructed from 4-ply reinforced high-temperature silicone for superior burst strength and long service life
• Meets and exceeds SAE J20 industry standards for heavy-duty pressure connections
• Excellent resistance to high operating temperatures — rated for demanding performance and forced-induction applications
• UV and ozone resistant — maintains flexibility and integrity over time even when exposed to the elements
• Suitable for marine, automotive, turbo, intercooler, intake, and industrial use
• Not compatible with fuel or oil — designed for air, water, and coolant applications only
• Finished in a clean black exterior for a professional under-hood or engine bay appearance

The HTSR-112-125-BLK silicone reducer hose coupler is a go-to solution for fabricators and enthusiasts building custom intake, intercooler, or cooling system plumbing. Its multi-ply silicone construction handles pressure spikes and temperature extremes that would quickly degrade standard rubber hoses, making it a reliable long-term upgrade for both street and performance builds.
