If you're diving into some serious engine work or just want to upgrade your cooling system, check out this HPS 5/8" (16mm) black high-temp reinforced silicone heater hose. This stuff is no joke; it's built to handle the heat and pressure that comes with high-performance applications. Whether you're working on a custom turbo setup, a DIY intake, or just need a reliable hose for your radiator, this 10-foot roll has got you covered.
What sets this hose apart? For starters, it's made from premium industrial-grade silicone that meets and exceeds SAEJ20 standards. That means it’s not just tough—it’s built for the long haul. The heavy wall design can handle extreme pressures, with a maximum working pressure of 70 psi, so you won’t have to worry about blowouts when things get hot under the hood. Plus, it’s ultra-flexible, which makes routing it around tight spaces a breeze.
Now, let’s talk specs. This hose operates in a temperature range from -65°F to a scorching 350°F (177°C), so it can handle whatever you throw at it. The inside diameter is 5/8" (16mm), and the outside diameter is 7/8" (22mm), giving it a solid build with a wall thickness of about 3mm. And don’t forget about the bend radius of just 3 inches—perfect for those tricky corners in your setup.
One thing to keep in mind: this silicone hose isn’t compatible with fuel or oil, so stick to water and antifreeze (like coolant) to keep things running smoothly. It’s also UV and ozone resistant, meaning it won’t crack or peel over time, even under harsh conditions.
