If you're diving into some serious engine work or custom turbo setups, the HPS 3-11/16" (93mm) High Temp Silicone Charge Air Cooler (CAC) Hose Coupler is a piece you won’t want to overlook. This isn't just any silicone hose; it's built tough with a 4-ply aramid reinforcement that can handle the heat—literally. With a temperature range from -65°F to a scorching 500°F (that's about 260°C for the metric folks), it’s designed to keep your charge air system running smoothly even under the most demanding conditions.
One of the things I really appreciate about this hose is how it manages slight misalignments. Whether you're working on a project in your garage or setting up a marine engine, it isolates vibrations like a champ. This feature really comes in handy when you’re fabricating custom turbo or intercooler piping; you want something that can flex a bit without compromising the connection.
Now, let’s talk specs. The inside diameter of this bad boy is 3-11/16" (93mm), and the outside diameter is about 4" (103mm). It stretches out to a solid 6" in length, so you’ve got plenty of room to work with. Plus, it’s got a wall thickness of 4.5mm, which gives it that extra durability. And for those worried about the elements, it’s UV and ozone resistant, so it won’t break down just from sitting in the sun.
Just a heads up, though—this silicone hose isn’t compatible with fuel or oil, so make sure you keep it in the right application. If you’re looking for a reliable, high-performance hose that meets and exceeds SAEJ20 industry standards, this is definitely worth considering. It’s got three rings for added security and stability, ensuring that your connections are tight and leak-free.
So whether you're tackling a high-performance build or just need a solid connection for your charge air system, the HPS Silicone CAC Hose Coupler is ready to take on the challenge.
