HPS Performance Products 3" (76mm) Black 4-Ply Silicone 45 Degree Elbow Coupler Hose - HTSEC45-300-BLK

If you're diving into some serious custom work, let me tell you about this HPS 3" (76mm) High Temp 4-ply Reinforced Silicone 45 Degree Elbow Coupler Hose. This isn't just any hose; it's built to handle the heat—literally. With a temperature range from -65°F to a scorching 350°F (177°C), it’s perfect for those high-pressure setups where reliability is key.

Constructed with a robust 4-ply design, this silicone hose is tough enough for heavy-duty applications. Whether you’re working on a marine project, setting up custom turbo or intercooler piping, or even piecing together a DIY intake or radiator cooling system, you can count on this elbow coupler to get the job done right. Just a heads up though, it’s not meant for fuel or oil—so keep that in mind while you’re planning your build.

Let’s get into the nitty-gritty. The inside diameter measures 3 inches (76mm), which fits snugly for most performance applications, while the outside diameter is 3.39 inches (86mm). Each leg is 4 inches long, giving you enough room to make those tight bends without stressing the hose. Plus, the 4.5mm wall thickness adds that extra durability you want in a high-performance setup.

And it’s not just about function; this hose looks good too, coming in a sleek black color that fits right in with any engine bay. It's also UV and ozone resistant, so you don’t have to worry about it breaking down under the sun or in harsh conditions.

Bottom line: if you need a reliable, high-temp silicone elbow coupler that can handle the heat and pressure while looking sharp, this HPS hose is a solid choice. Just make sure to pair it with the right components, and you’ll be set for whatever project you’re tackling.
