If you're diving into a project that involves high temperatures and heavy-duty pressure connections, let me tell you about this HPS 5/32" Black Silicone Heater Hose. This stuff is the real deal. I’ve used it in my own setups, and it’s hard to beat when it comes to performance and durability.
First off, the quality is evident. Made from premium industrial-grade silicone, this heater hose can handle extreme conditions—think temperatures from -65°F all the way up to 350°F. That’s not just marketing fluff; it’s designed to meet and exceed SAEJ20 standards, which is a must if you're working on anything from marine applications to custom turbo setups.
One of the things I love about this hose is its heavy wall design. It’s built to withstand high pressure, with a max working pressure of 85 psi. Plus, it’s ultra-flexible, making it easy to route in tight spaces without worrying about kinks. The bend radius is just 3/4", so you can maneuver it around corners without a hitch.
Now, I should mention that this silicone hose isn’t compatible with fuel or oil, but it shines when it comes to water and anti-freeze, like coolant. So, if you’re looking to upgrade your radiator cooling system or need something for your DIY intake, this is a solid choice.
Another perk? It’s resistant to ozone and UV rays, meaning it’s not going to crack or peel over time. I’ve seen hoses fail in the sun, but not this one. And with a wall thickness of 3mm, it’s got the burst strength to back it up.
To top it all off, it comes in a continuous 10-foot roll, so you won’t be stuck piecing together sections. Just cut what you need and go. If you’re serious about your build, this HPS silicone heater hose is worth considering.
