HPS Performance Products 1.25" (32mm) Black 4-Ply Reinforced Silicone Straight Coupler Hose
$10.66

If you’re diving into some serious engine work or just want to upgrade your cooling system, the HPS 1-1/4" (32mm) 3" Long High Temp 4-ply Reinforced Black Silicone Straight Coupler Hose is a solid choice. This isn’t just any old hose; it’s built to take the heat—literally. With a temperature range that can handle from -65°F all the way up to 350°F (that’s about 177°C for the metric folks), it’s tough enough for heavy-duty pressure connections. You won’t have to worry about it failing on you when the engine gets hot.

I’ve used these hoses in a couple of custom turbo setups and let me tell you, they hold up beautifully. The 4-ply reinforcement means they’re built to last, and they meet the SAEJ20 industry standards, which is a big deal in the automotive world. Whether you’re fabricating intercooler piping or working on a DIY intake system, this hose is up for the task.

One of the things I really appreciate is the UV and ozone resistance. If you’re working in a marine setting or just want to make sure your setup can handle the elements, this hose has got your back. Just keep in mind, it’s not compatible with fuel or oil, so plan accordingly if you’re working on something that requires those fluids.

Here’s a quick rundown of the specs: you’re looking at an inside diameter of 1.25 inches (32mm) and an outside diameter of 1.66 inches (42mm). The hose length is a handy 3 inches, and the wall thickness is around 4.5mm (give or take). It’s black, so it looks sleek in any engine bay, and it’s just the right size for a variety of applications.

Features:

  • Made of High Temperature 4-ply Reinforced Silicone
  • Meets and exceeds SAEJ20 industry standards
  • Perfect for heavy-duty pressure connections
  • Great for marine and industrial use
  • Ideal for custom turbo or intercooler piping fabrication
