If you're diving into some serious custom work or just need to replace a worn-out hose, the HPS 3-1/4" (83mm) High Temp 4-ply Reinforced Blue Silicone Hump Coupler Hose is a solid choice. This isn't just any silicone hose; it's built tough to handle heavy-duty pressure connections and high temperatures, making it perfect for those high-performance setups.

With a temperature range that goes from -65°F to a scorching +350°F (that’s about 177°C for the metric folks), you know it can take the heat without breaking a sweat. The 4-ply reinforcement gives it that extra muscle, so you can trust it to hold up under pressure—literally. Plus, it compensates for misalignment and helps reduce vibration, which is a lifesaver in custom builds where everything needs to fit just right.

This hose measures 3" long, with an inside diameter of 3.25" (83mm) and an outside diameter of 3.67" (93mm). The wall thickness is about 4.5mm, which gives it that rugged feel. It's also UV and ozone resistant, so you won’t have to worry about it degrading over time if it’s exposed to the elements.

Just keep in mind, this silicone hose isn’t compatible with fuel or oil, so save it for your intake or radiator cooling system, or even for turbo and intercooler piping fabrication. It’s great for marine and industrial applications too, making it a versatile option for various projects.

  • Made of High Temperature 4-ply Reinforced Silicone
  • Exceeds SAEJ20 industry standards for heavy-duty connections
  • Ideal for custom turbo or intercooler piping, DIY intake, and radiator systems
  • Compensates for misalignment and offsets vibration
  • UV and ozone resistant
  • Not compatible with fuel or oil

So if you're looking for a reliable, high-temp hose that can handle the rigors of performance applications, this HPS hump coupler is worth considering. It’s got the specs to back it up and the durability you need for your next project.
