If you're diving into the world of custom builds or just need a solid solution for your piping needs, let me tell you about this HPS 3" (76mm) High Temp 4-ply Reinforced Silicone 180 Degree U Bend Elbow Coupler Hose. This isn't your run-of-the-mill hose; it’s built tough to handle some serious heat and pressure. Whether you're working on a turbo setup, a custom intercooler, or even a DIY radiator cooling system, this elbow has got your back.
First off, this hose is designed to meet and exceed SAEJ20 industry standards. What does that mean for you? It means you're getting a product that can handle heavy-duty pressure connections without breaking a sweat. The temperature range is impressive, too—operating smoothly from -65°F to a blistering 350°F (that’s about 177°C for those who like their metrics). So, whether you're in a chilly garage or under the hot sun, this hose will keep its cool.
Now, let’s get into the nitty-gritty of the specs. The inside diameter is 3" (76mm), and the outside diameter is 3.39" (86mm). Each leg is a handy 4-1/2" long, and the center line radius is also 4-1/2". You’ll find that it fits snugly without any fuss when you're piecing together your setup. The overall height of 11-1/2" gives you plenty of room to work with, and the wall thickness is about 4.5mm, which adds that extra layer of durability.
One of the standout features is its construction. This hose is made with a 4-ply high-temp reinforced silicone, which means it’s not just tough; it’s also UV and ozone resistant. This is a big deal if your setup is exposed to the elements. Just keep in mind, while it’s great for water and coolant, don’t even think about using it with fuel or oil—it’s just not compatible.
So whether you’re in the marine world, tackling industrial projects, or just getting creative with your car's intake system, this elbow coupler hose is a reliable choice. It’s practical, it’s robust, and it’s built for those who want to get things done right.
