If you’re diving into some serious engine work or just need to upgrade your cooling system, let me tell you about this HPS 3/4" (19mm) red high-temp reinforced silicone heater hose. This isn’t just any hose; it’s a solid 10-foot roll of reliability that meets and exceeds the SAEJ20 industry standards. Trust me, when you’re dealing with high-pressure connections, you want something that can take the heat—and this hose does just that.
What I love about this silicone heater hose is its heavy wall design. It’s built to handle extreme pressure without breaking a sweat. You’ll find it ultra-flexible, which makes installation a breeze, even in tight spots. Plus, its tensile strength means it can take a beating without giving in. Whether you’re fabricating custom turbo piping, setting up an intercooler, or just looking to spruce up your DIY intake or radiator cooling system, this hose has got your back.
Now, let’s get into the nitty-gritty. This hose can handle temperatures ranging from -65°F to a scorching 350°F (that’s about 177°C for the metric folks). With an inside diameter of 3/4" (19mm) and an outside diameter of 1" (25mm), it fits perfectly into most setups. The max working pressure? A solid 70 psi. And when it comes to bends, you’re looking at a bend radius of just 3 inches, which is pretty handy for tight configurations.
One thing to keep in mind is that this silicone hose isn’t compatible with fuel or oil, but it works like a champ with water and anti-freeze. So, if you’re dealing with coolant, you’re in the clear. Plus, it’s resistant to UV rays and ozone, so you know it’s going to last. You won’t have to worry about cracking, peeling, or aging, which is a huge plus in the long run.
In short, if you’re serious about performance and durability, this HPS silicone heater hose is a solid choice. It’s not just a hose; it’s a piece of gear you can trust to keep your engine running cool and efficient.
