If you're diving into some serious DIY projects or need a solid upgrade for your cooling systems, check out this HPS 2-11/16" (68mm) x 3 Feet Long High Temp 4-ply Reinforced Black Silicone Tube Coupler Hose. This isn’t just any hose; it’s built tough to handle the heat and pressure that comes with high-performance setups. Seriously, it meets and even exceeds those SAEJ20 industry standards, so you know it's going to hold up under stress.
What’s great about this coupler hose is its versatility. Whether you're working on custom turbo piping, intercooler setups, or even a DIY intake for your project car, this hose has got your back. It can handle temps from -65°F to a scorching +350°F (that’s about 177°C for those who prefer metric), making it perfect for a variety of high-temperature applications. Just keep in mind, this silicone hose isn’t meant for fuel or oil, so don’t go mixing it up with your fuel lines.
Now, let’s talk specs. You’re looking at a 4-ply reinforced design that gives it some serious durability. The inside diameter is 2.69 inches (68mm), and it has an outside diameter of 3.07 inches (78mm), which means it fits snugly where you need it without any fuss. At 3 feet long, it gives you plenty of length to work with, and the 4.5mm wall thickness adds that extra bit of strength you want in a hose that’s going to be under pressure.
Plus, this hose is UV and ozone resistant, so if you’re using it in an outdoor setup, it’s not going to degrade in the sun. It’s all black, too, which gives it that sleek look that fits right in with any engine bay or custom build. Just remember, if you’re looking for something to handle oil or fuel, you’ll need to look elsewhere.
In short, if you need a reliable, high-temp silicone hose for your next project, this HPS coupler is a solid choice. It’s built for heavy-duty connections and can take the heat, literally. Get ready to tackle those upgrades with confidence!
