If you’re diving into a project that needs a solid heater hose, let me tell you about the HPS 5/32" Blue Silicone Heater Hose. This stuff is a game-changer, especially if you’re dealing with high temps and pressure. I’ve used it for various applications, and it’s held up like a champ.
First off, this hose is made from premium industrial-grade silicone, so you know it’s tough. It’s got a heavy wall design that can handle some serious pressure—up to 85 psi, in fact. Whether you’re fabricating custom turbo setups or just need something reliable for your radiator cooling system, this hose fits the bill. Plus, it’s ultra-flexible, which makes installation a breeze, even in tight spots.
One of the standout features is its temperature range. It can handle temperatures from -65°F to a scorching 350°F (that’s about 177°C for the metric folks). So, if you’re worried about it melting or cracking under heat, you can put those fears to rest. The bend radius is 3/4", which gives you some leeway when routing it through your setup.
Now, a quick heads-up: this silicone hose isn’t meant for fuel or oil—so keep that in mind. But it works great with water and antifreeze, making it perfect for cooling systems. It’s also resistant to ozone and UV rays, which is a nice touch if your setup sees a lot of sun or harsh conditions.
The hose comes in a generous 25-foot roll, shipped as a single continuous piece, so you won’t have to deal with annoying joints or sections. Just cut what you need and go! And let’s not forget about the color—this vibrant blue not only looks good but also stands out in your engine bay.
In short, if you’re looking for a reliable, high-performance heater hose that can take the heat and pressure, the HPS 5/32" Blue Silicone Heater Hose is worth checking out. It’s built to last and designed for those who know what they’re doing. You won’t be disappointed.
