Hey there! If you're diving into some serious DIY projects or just need a solid coupler hose for your ride, let me tell you about the HPS 5/8" (16mm) x 3 Feet Long High Temp 4-ply Reinforced Black Silicone Tube Coupler Hose. This isn’t just any hose; it’s built to handle the heat and pressure that comes with high-performance setups.
This silicone hose meets and even exceeds the SAEJ20 industry standards, so you know it’s tough. It’s perfect for heavy-duty pressure connections, whether you’re working on a custom turbo setup or fabricating intercooler piping. Plus, if you’re into marine or industrial applications, this hose has you covered there too.
Now, let’s get into the nitty-gritty. It has a temperature range that spans from -65°F to a scorching +350°F (that’s about 177°C for those who prefer metric). So, whether you’re in a chilly garage or dealing with some serious heat under the hood, this hose can take it. The 4-ply reinforcement gives it the durability you need, with a wall thickness of around 4.5mm, which is pretty hefty for a silicone hose.
In terms of dimensions, the inside diameter is a snug 5/8" (16mm), while the outside diameter measures about 1.03" (26mm). And at a length of 3 feet, you’ve got plenty of material to work with for your projects. Just keep in mind, this hose is UV and ozone resistant, so it won’t break down on you when exposed to the elements.
One important thing to remember: this silicone hose isn’t compatible with fuel or oil, so save it for coolant or air applications. It’s a fantastic choice for those looking to upgrade their intake or radiator cooling systems without breaking the bank.
