HPS Performance Products 3.5 to 4 Inch Blue 4-Ply Silicone 45 Degree Elbow Reducer Hose - HTSER45-350-400-BLUE

If you're diving into some serious DIY projects or just need a reliable hose for your rig, the HPS 3-1/2" - 4" High Temp 4-ply Reinforced Silicone 45 Degree Elbow Reducer Coupler Hose is a solid choice. I’ve put this thing through its paces, and let me tell you, it’s built to last. This isn’t just any silicone hose; it’s designed to meet and exceed SAEJ20 standards, which means it can handle some heavy-duty pressure without breaking a sweat.

What I really appreciate about this hose is its versatility. Whether you’re working on a custom turbo setup, fabricating intercooler piping, or tinkering with your DIY intake or radiator cooling system, this elbow reducer has got your back. It can handle temperatures ranging from a chilly -65°F all the way up to a scorching 350°F (that’s about 177°C for those of you who prefer metric). So, if you’re in a high-temp environment, you won’t have to worry about it losing its form or function.

The 4-ply reinforcement is no joke either. It adds a level of durability that you can feel when you’re installing it. The inside diameter ranges from 3.5" to 4" (or 89mm to 102mm), and the outside diameter is between 3.9" and 4.41" (99mm to 112mm). Plus, with a wall thickness of around 4.5mm, you know it’s not going to collapse under pressure. The leg length is a convenient 4 inches on each side, making it easy to fit into your existing setup.

And let’s not forget about the color—this vibrant blue isn’t just for looks; it’s also UV and ozone resistant. Just keep in mind that while it’s tough against heat and pressure, this silicone hose isn’t compatible with fuel or oil, so plan your setup accordingly.

In short, if you’re looking for a reliable, high-performance silicone hose that can take the heat (literally), the HPS 45 Degree Elbow Reducer is worth considering. It’s rugged, versatile, and ready to tackle whatever project you throw at it.
