If you’re diving into a project that needs a solid heater hose, you might want to check out this HPS 3/4" (19mm) black high-temp reinforced silicone heater hose. This stuff isn’t just your run-of-the-mill hose; it’s built to handle the heat—literally. With a max temperature rating of 350°F and a working pressure of up to 70 psi, it’s designed for heavy-duty applications. Whether you're working on a custom turbo setup or just need something reliable for your radiator cooling system, this hose has got you covered.
What I really appreciate about this hose is its heavy wall design. It can take a beating and still perform like a champ, making it perfect for those extreme pressure connections. Plus, it’s ultra-flexible, which means you can bend it around corners without worrying about kinks or breaks. The tensile strength is impressive too, so you know it’s not going to give up on you when you need it most.
This hose is made from premium industrial-grade silicone, which means it’s not just tough—it’s also resistant to coolants, aging, and ozone. Just keep in mind, it’s not compatible with fuel or oil, but it works great with water and antifreeze, so it’s ideal for cooling systems.
Another nice touch is that it comes in a single continuous roll of 100 feet. No more fussing with multiple sections—just cut what you need and get to work. The black color gives it a sleek look, too, which is always a plus in my book.
Here's a quick rundown of the specs: it has an inside diameter of 3/4" (19mm) and an outside diameter of 1" (25mm). The wall thickness is about 4mm, and it has a bend radius of 3 inches. So whether you’re into marine applications, industrial use, or just tackling a DIY project, this hose is definitely worth considering.
