If you’re diving into a project that needs a reliable heater hose, let me tell you about the HPS 7/8" (22mm) Clear High Temp Reinforced Silicone Heater Hose. This isn’t just any hose; it’s a solid 100-foot roll of high-quality silicone that’s built to take a beating. I’ve used it for everything from custom turbo setups to radiator cooling systems, and it hasn’t let me down yet.
First off, the material is top-notch. It’s made from industrial-grade silicone that meets and even exceeds SAEJ20 standards, which is a big deal if you’re looking for durability. The heavy wall design means it can handle extreme pressure without breaking a sweat—up to 60 psi to be exact. And when it comes to temperature, this hose can handle anything from -65°F to +350°F (that’s about 177°C for you metric fans), making it perfect for high-temperature applications.
One thing I really appreciate is the flexibility of this hose. It bends easily with a 4-inch bend radius, so you can fit it into tight spots without worrying about kinks. Plus, the tensile strength is impressive; it won’t crack or peel over time like some cheaper options out there. It’s also resistant to UV rays and ozone, which is a nice touch if you’re using it in a marine environment.
Now, a quick heads-up: this silicone hose isn’t compatible with fuel or oil, so keep that in mind. However, it works great with water and antifreeze, making it a solid choice for coolant systems. I’ve used it in various setups, and it holds up wonderfully against coolants and prevents cold leaks.
In short, if you’re looking for a robust, high-performance heater hose that’s easy to work with and built to last, the HPS 7/8" Clear Silicone Heater Hose is worth considering. It comes in one continuous roll, so you won’t have to deal with multiple sections, which is a huge plus when you’re trying to keep things tidy.
