HPS Performance Products 5 Inch 4-Ply Reinforced Black Silicone Straight Coupler Hose 3" Long
$28.41

Alright, let’s talk about the HPS 5" (127mm) High Temp 4-ply Reinforced Black Silicone Straight Coupler Hose. If you’re diving into some serious projects, whether it’s for your boat, a custom turbo setup, or just upgrading your radiator cooling system, this hose is a solid choice. It’s built tough to handle the heat, with a max temperature rating of 350°F (177°C). So, if you’re pushing your engine hard, you won’t have to worry about this thing melting down on you.

What’s really cool is the 4-ply construction. This isn’t just some flimsy silicone; it’s designed to take on high-pressure connections without flinching. The inside diameter is a generous 5" (127mm), perfect for those larger piping needs. And with a wall thickness of around 4.5mm, it’s got the strength to back it up. Just keep in mind, this hose isn’t compatible with fuel or oil, so plan your setup accordingly.

Now, if you’re looking at fitment, this hose clears quite a few custom applications, especially if you're fabricating your own intake or intercooler piping. It’s also UV and ozone resistant, so it can handle the elements if you’re using it in a marine environment. Just be aware, if you’re looking for something to handle fuel, you’ll need to look elsewhere.
