Alright, let’s talk about the HPS 2-3/4" - 3-1/2" (70mm - 89mm) 4-ply Reinforced Silicone Reducer Coupler Hose. If you’re diving into some serious automotive or marine projects, this is the kind of gear you want in your toolkit. I’ve used a few different hoses over the years, and I can tell you that this one really stands out.
First off, the construction is solid. It’s made from high-temperature 4-ply reinforced silicone, which means it’s built to handle some serious heat—up to 350°F (177°C). That’s crucial if you’re pushing your engine hard or working on custom turbo setups. This hose isn’t just about withstanding high temperatures, though. It meets and exceeds SAEJ20 industry standards, so you know it’s reliable for heavy-duty pressure connections.
The versatility of this hose is impressive. Whether you’re fabricating custom turbo or intercooler piping, or even working on a DIY intake or radiator cooling system, it’s got your back. Plus, it’s UV and ozone resistant, so you don’t have to worry about it degrading over time. Just keep in mind that it's not compatible with fuel or oil—so save that for your fuel lines.
Now, let’s get into the nitty-gritty specs. The inside diameter ranges from 2.75" to 3.5" (or 70mm to 89mm), and the outside diameter is between 3.12" and 3.9" (80mm to 99mm). It’s a compact 3" long, making it easy to fit into tight spaces. The wall thickness is about 4.5mm, which adds to its durability without being overly bulky.
In a nutshell, if you’re looking for a reliable, high-performance silicone hose that can take the heat and handle some serious pressure, the HPS reducer coupler is worth considering. It’s not just another piece of rubber; it’s engineered for performance and built to last.
