Hey there, fellow gearheads! If you're diving into some serious engine work or just need a reliable silicone hose for your custom setup, let me tell you about the HPS 1" (25mm) Silicone Hump Coupler Hose. This isn't just any hose—it's built tough with a 4-ply Aramid reinforcement that can handle the heat, literally. We're talking about temperatures from a chilly -65°F all the way up to a scorching 500°F (260°C). So, whether you're fabricating a custom turbo setup or just need something solid for your radiator, this hose has got your back.
What really sets this hose apart is its ability to compensate for misalignment. If your piping isn’t perfectly straight, no worries—this coupler can handle those little quirks without skipping a beat. Plus, it does a great job of dampening vibrations, which is a lifesaver in high-performance applications.
Now, let’s get into the nitty-gritty. The inside diameter is a snug 1" (25mm), and it stretches out to 1.38" (35mm) on the outside. With a length of 6", it fits nicely into a variety of setups. Just a heads up, though: this silicone hose isn’t compatible with fuel or oil, so keep that in mind when planning your project. But it works like a charm with water and coolant, making it a solid choice for your cooling system needs.
And if you’re working in a marine or industrial environment, this hose is UV and ozone resistant, so you know it can take a beating. It's designed to meet and exceed SAEJ20 industry standards, which means it’s built for heavy-duty pressure connections. You can trust it to perform when you really need it.
So, if you're looking for a reliable, high-temp silicone hose that can handle the rigors of your custom projects, check out the HPS Hump Coupler Hose. It's a solid piece of kit that won’t let you down!
