If you're diving into some serious projects, you might want to check out this HPS 1/2" (13mm) Black high-temp reinforced silicone heater hose. It's not just another hose; this thing is built to last and handle the heat. We're talking about a solid 10-foot roll that meets and exceeds SAEJ20 industry standards, so you know it’s got the chops for heavy-duty pressure connections.
What really sets this hose apart is its construction. Made from premium industrial-grade silicone, it’s got a heavy wall design that can take on extreme pressure without breaking a sweat. Whether you’re working on a marine setup, fabricating custom turbo piping, or just need something reliable for your DIY intake or radiator cooling system, this hose has you covered.
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 1/2" (13mm) and an outside diameter of 3/4" (19mm), it’s got a max working pressure of 80 psi. Plus, the bend radius is a neat 2-1/2", which makes it pretty flexible for tight spots. The wall thickness is about 3mm, giving it that extra durability you want when the heat is on.
Now, a quick heads-up: this silicone hose isn’t compatible with fuel or oil, but it plays nicely with water and coolant. So if you’re dealing with anti-freeze, you’re in the clear. It’s also resistant to coolants, cold leaks, cracking, peeling, aging, and ozone, so you won’t have to worry about it degrading on you over time.
In short, if you need a reliable, high-performance hose that can take the heat, this HPS silicone heater hose is worth a look. It ships in one continuous roll, so you won’t have to deal with piecing together multiple sections. It’s black, it’s tough, and it’s ready to tackle whatever you throw at it.
