HPS Performance Products 3.5 to 3.75 Inch Blue 4-Ply Silicone Reducer Coupler Hose 6 Inch Long
$94.85

If you're diving into some serious custom work, you’re going to want a solid reducer coupler hose, and let me tell you, this HPS 3.5 to 3.75-inch silicone reducer is a gem. Measuring 6 inches long, it’s built to handle the heat—literally. With a temperature range that swings from -65°F to a scorching +350°F, this hose is no joke when it comes to high-temp applications.

What’s really cool about this hose is its 4-ply reinforced design. That means it’s tough enough for all those heavy-duty pressure connections you might be working with, whether you're fabbing up some custom turbo piping or tinkering with your DIY intake or radiator cooling system. And don’t worry about UV damage or ozone wear; this thing is made to last.

Just a heads up though—this silicone hose isn’t meant for fuel or oil, so keep that in mind when you’re planning your setup. It fits snugly with an inside diameter range of 3.5 to 3.75 inches (89mm to 95mm) and an outside diameter of about 3.9 to 4.13 inches (99mm to 105mm). The wall thickness is a sturdy 4.5mm, so you know it’s built to withstand some serious pressure.

In a nutshell, if you’re looking for a reliable, high-performance silicone hose that can handle the heat and keep your project on track, this HPS reducer coupler is a solid choice.
