If you’re diving into some serious turbo or intercooler projects, you might want to check out the HPS 5" (127mm) High Temp 4-ply Aramid Reinforced Silicone Charge Air Cooler (CAC) Hose Coupler for the hot side. This isn’t just any silicone hose; it’s built to take the heat—literally. With a temperature range that can handle anything from a chilly -65°F to a scorching 500°F (about 260°C), it’s ready for whatever your engine throws at it.
What sets this hose apart is its 4-ply aramid construction. It’s not just tough; it’s designed to meet and even exceed SAEJ20 industry standards. That means you can trust it to deliver a solid connection between your engine-mounted charge air system components. Plus, it’s great for those slight misalignments that happen in the real world. If your setup has a bit of wiggle, this hose can handle it without a hitch.
Another bonus is its ability to isolate vibrations between hose ends, which is a must if you want to keep things running smoothly. Whether you’re working on a custom turbo setup or fabricating intercooler piping, this hose will do the job without fuss. And for those of you who might be working in marine or industrial applications, it’s built tough enough to withstand the elements. It’s UV and ozone resistant, so you don’t have to worry about it breaking down in the sun.
Just a heads up, though: this silicone hose isn’t compatible with fuel or oil, so keep that in mind when you’re planning your setup. The inside diameter is a solid 5" (127mm), and the outside measures 5.39" (137mm), giving you a nice, snug fit. It’s 6" long with a wall thickness of around 4.5mm (give or take). Oh, and it comes with three rings for added security.
In short, if you’re looking for a reliable, high-performance silicone hose that can take the heat and keep your project on track, the HPS 5" 4-ply Reinforced Aramid CAC Charge Air Cooler Hose Coupler is a solid choice.
