If you're diving into a project that needs some solid connections, check out the HPS 1-1/4" (32mm) High Temp Straight Coupler Hose. This isn’t just any silicone hose; it’s built tough with a 4-ply reinforced design that stands up to some serious heat—up to 350°F, to be exact. Whether you're working on a custom turbo setup or just need something reliable for your radiator cooling system, this hose has got your back.

One of the standout features is its ability to handle heavy-duty pressure connections without breaking a sweat. It meets and even exceeds SAEJ20 standards, so you know it’s up to the task.
