HPS Performance Products 2.75 to 4 Inch Black Silicone 45 Degree Elbow Reducer Hose
$93.73

If you're diving into some serious custom work, the HPS 2-3/4" - 4" High Temp 4-ply Reinforced Silicone 45 Degree Elbow Reducer Coupler Hose is a solid choice. This isn't just any hose; it's built tough to handle heavy-duty pressure connections, making it perfect for high-temperature setups. Whether you’re fabricating a custom turbo system or just need a reliable hose for your DIY intake or radiator cooling, this elbow reducer has got your back.

What sets this hose apart? Well, it’s made from a high-temperature 4-ply reinforced silicone that meets and exceeds SAEJ20 industry standards. That means you can trust it to hold up under pressure and high heat—up to 350°F (177°C) to be exact. The inside diameter ranges from 2.75" to 4" (70mm to 102mm), so it’s versatile enough to fit various applications. The outside diameter stretches from 3.12" to 4.41" (80mm to 112mm), which is ideal for snug connections without compromising flow.

Each leg of the hose is 4 inches long, and with a wall thickness of about 4.5mm, it’s built to withstand the rigors of both marine and industrial environments. Plus, it’s UV and ozone resistant, so you don’t have to worry about it degrading over time. Just a heads-up, though: this silicone hose isn’t compatible with fuel or oil, so keep that in mind when planning your setup.

Key Features:

  • Constructed from high-temperature 4-ply reinforced silicone
  • Meets SAEJ20 standards for heavy-duty pressure connections
  • Perfect for custom turbo, intercooler piping, and DIY projects
  • UV and ozone resistant for durability
  • Not suitable for fuel or oil applications
