If you're diving into a project that requires a reliable heater hose, let me tell you about the HPS 7/8" (22mm) Black High Temp Reinforced Silicone Heater Hose. This stuff is the real deal—perfect for those heavy-duty connections where you can't afford to cut corners. I’ve used it for everything from custom turbo setups to radiator cooling systems, and I can confidently say it’s built to last.
First off, this hose is made from premium industrial-grade silicone. It’s designed to handle some serious heat, with a temperature range that goes from a chilly -65°F all the way up to a scorching 350°F (that’s about 177°C for you metric folks). And if you’re worried about pressure? No sweat. It boasts a max working pressure of 60 psi, so you know it can take a beating without bursting.
The heavy wall design is a game-changer. It not only gives you excellent tensile strength but also means you can bend it without worrying about kinks. Speaking of bending, it has a bend radius of just 4 inches, which is pretty impressive for a hose this robust. Plus, it’s UV and ozone resistant, so it can handle whatever the elements throw at it.
Now, a quick heads-up: this silicone hose isn’t compatible with fuel or oil, but it works like a charm with water and antifreeze. So if you’re working on a cooling system, you’re in good hands. And one of the best parts? It comes in a single continuous roll of 10 feet, so you won't be piecing together multiple sections like a jigsaw puzzle.
In summary, if you need a heater hose that’s tough enough for marine and industrial applications, or if you're just a DIYer looking to upgrade your setup, this one checks all the boxes. It's got high burst strength, excellent heat resistance, and it’s resistant to coolants, cracks, and aging. You won't be disappointed.
