If you’re diving into a project that needs a solid heater hose, the HPS 1" (25mm) blue high temp reinforced silicone hose is worth your attention. This isn’t just any hose; it’s built to handle some serious heat and pressure, making it a go-to for those heavy-duty applications.
First off, let’s talk about the construction. This hose is made from premium industrial-grade silicone that meets and even exceeds SAEJ20 standards. You’re looking at a heavy wall design that can tackle extreme pressure, so you won’t have to worry about it blowing out on you. Plus, it’s ultra-flexible with excellent tensile strength, which is a lifesaver when you’re trying to fit it into tight spaces.
Now, about the numbers: it can handle temperatures from -65°F to a scorching 350°F (177°C). That’s right, whether you’re working on a custom turbo setup or just need to replace your radiator hose, this hose has got your back. The inside diameter is 1" (25mm), and with an outside diameter of about 1.3" (33mm), it’s perfect for most standard fittings. Just keep in mind that it has a max working pressure of 50 psi and a bend radius of 4.5 inches, so plan your routing accordingly.
And here’s a little tip: while it’s compatible with water and antifreeze (coolant), steer clear of fuel or oil. This hose is designed for cooling applications, so it’s not the best choice for anything else.
When you order this hose, it’s sold by the foot, and you’ll get it in one continuous roll—no annoying cuts or sections to deal with. It’s also resistant to cracking, peeling, and aging, so you can count on it lasting through the seasons.
So, if you’re looking for a reliable hose that won’t let you down, give this HPS silicone heater hose a shot. It’s built for the long haul, and you’ll appreciate the quality when you’re out there on the road or water.
