HPS Performance Products 3.5" Blue 4-Ply Reinforced Silicone Hump Coupler Hose 4" Length
$50.38

If you're diving into some serious DIY projects or just need to upgrade your ride, the HPS 3-1/2" (89mm) High Temp 4-ply Reinforced Blue Silicone Hump Coupler Hose is a solid choice. Trust me, this isn't just any hose—it's built to handle the heat and pressure that come with high-performance setups. Whether you're working on a custom turbo system or fabricating intercooler piping, this hose has got your back.

One of the coolest things about this coupler is its ability to compensate for misalignment. If your setup isn't perfectly straight, no worries! This hose can handle the vibrations and offsets, keeping everything snug and secure. Plus, it’s made from a tough 4-ply silicone that meets and exceeds the SAEJ20 standards. That means you can count on it for heavy-duty pressure connections without breaking a sweat.

Now, let’s talk numbers. This hose has an inside diameter of 3.5 inches (or 89mm) and an outside diameter of 3.9 inches (99mm). With a length of 4 inches and a wall thickness of about 4.5mm, it’s sturdy enough for whatever you throw at it. And don’t worry about it falling apart under pressure; it can handle temperatures from -65°F up to a scorching 350°F (177°C). Just keep in mind, it’s not compatible with fuel or oil, so steer clear of those applications.

What’s more, this hose is UV and ozone resistant, making it suitable for marine and industrial use as well. So whether you're upgrading your radiator cooling system or tackling a DIY intake project, this blue beauty will not only perform but also add a pop of color to your setup.
