If you’re diving into a project that needs a solid heater hose, let me tell you about the HPS 1/2" (13mm) Clear High Temp Reinforced Silicone Heater Hose. This stuff is the real deal—10 feet of pure reliability that’s built to handle some serious heat. It meets and even exceeds the SAEJ20 industry standards, which is a big plus if you're working on anything heavy-duty. Whether you’re tackling a custom turbo setup, fabricating some intercooler piping, or just need something tough for your radiator cooling system, this hose has got your back.
What I love about this hose is its heavy wall design. It’s not just about looks; it can handle extreme pressure like a champ, making it ultra-reliable for all those high-temperature applications. And let’s not forget the flexibility—this hose bends like a pro, which is a lifesaver when you're trying to fit it into tight spaces.
Now, here are some specs that might interest you: it can handle temperatures ranging from -65°F to a scorching 350°F (that’s about 177°C for those of you who prefer metric). With an inside diameter of 1/2" (13mm) and an outside diameter of 3/4" (19mm), it’s a perfect fit for a lot of setups. The max working pressure is 80 psi, so you know it won’t buckle under stress. Plus, it has a bend radius of just 2-1/2", which is pretty impressive.
One thing to keep in mind, though—this silicone hose isn’t compatible with fuel or oil, so save it for water and antifreeze. But when it comes to coolants, it’s a warrior. It resists cracking, peeling, and aging, and it’s also UV and ozone resistant, which is a must if you’re using it outdoors.
In short, if you're looking for a reliable, high-performance silicone heater hose that won’t let you down, this is it. It ships as one continuous roll, so you won’t have to mess around with multiple sections. Grab this hose, and you’ll be set for whatever project you’ve got cooking!
