If you're diving into some serious engine work or just looking to upgrade your setup, the HPS 4" Long High Temp Silicone Hump Coupler Hose is definitely worth a look. This isn't just any hose; it's built tough with a 4-ply aramid reinforced design that can handle the heat—literally. We're talking a temperature range from a chilly -65°F all the way up to a blistering 500°F (that's about 260°C for the metric folks), so whether you're in a hot engine bay or dealing with extreme conditions, this hose has got your back.
The 4-inch inside diameter (102mm) is perfect for those heavy-duty pressure connections, and it meets or even exceeds SAEJ20 industry standards. That means you can trust it for marine applications, industrial setups, or even your custom turbo and intercooler piping projects. Plus, if you're into DIY, this hose is a solid choice for intake or radiator cooling systems.
One of the standout features of this coupler is its ability to compensate for misalignment and absorb vibrations, which is a game changer when you’re pushing your vehicle to its limits. And let’s not forget about its resilience; it’s UV and ozone resistant, so it won’t break down under the sun or in harsh environments. Just a heads-up, though: this silicone hose isn’t compatible with fuel or oil, but it plays nice with water and antifreeze, so you can use it without worry in those applications.
So if you're looking for a reliable, high-performance silicone hose that can handle the heat and the pressure, the HPS 4" Hump Coupler Hose might just be the piece you need to complete your setup. Trust me, once you’ve got this installed, you’ll notice the difference in your rig.
