HPS Performance Products 1.75" (45mm) Blue 4-Ply Reinforced Silicone Straight Coupler Hose 4" Long
$14.21

If you're diving into some serious DIY projects or just need a reliable coupler for your high-performance setup, let me tell you about this HPS 1-3/4" (45mm) Silicone Straight Coupler Hose. It's not just any hose; it's a solid piece of engineering that really stands up to the heat—literally. With a temperature range that swings from a chilly -65°F all the way up to a scorching 350°F (that’s about 177°C for the metric folks), this bad boy is built to handle whatever you throw at it.

What I love about this coupler is its 4-ply reinforced design. That means it’s tough enough for heavy-duty pressure connections without breaking a sweat. Whether you’re fabricating custom turbo or intercooler piping, or setting up a DIY intake or radiator cooling system, this hose has got your back. It's also UV and ozone resistant, which is a big plus if you're working in environments where those factors come into play.

Now, let’s talk specs. The inside diameter measures 1.75 inches (or 45mm), while the outside diameter is about 2.17 inches (55mm). It’s 4 inches long, with a wall thickness of around 4.5mm, so you know it’s not going to collapse under pressure. Just a heads-up, though—this silicone hose isn’t compatible with fuel or oil, so keep that in mind when planning your setup.

In short, if you need a reliable, high-temp hose that meets and exceeds SAEJ20 industry standards, this HPS coupler is worth considering. It’s versatile enough for marine and industrial applications, and it’s built to last. You won’t be disappointed.
