HPS Performance Products 1 3/8" Blue 90 Degree Elbow Coupler Silicone Hose 4-Ply Reinforced
$35.69

If you’re diving into some serious DIY projects or just need a reliable hose for your ride, the HPS 1-3/8" (35mm) High Temp 4-ply Reinforced Silicone 90 Degree Elbow Coupler Hose is a solid choice. I’ve had my hands on this piece for a while now, and I can tell you—it’s built to last. This isn’t just any silicone hose; it’s engineered to handle the heat, literally. With a temperature range from -65°F to a scorching +350°F (that’s about 177°C for those of you who prefer metric), it’s perfect for those high-pressure connections you might encounter in marine applications or even in your custom turbo setups.

The 4-ply reinforcement means it’s tough enough to withstand heavy-duty use without breaking a sweat. I’ve used it for everything from intercooler piping to DIY radiator cooling systems, and it hasn’t let me down yet. The inside diameter of 1.38 inches (35mm) fits snugly, while the outside diameter measures 1.75 inches (45mm), giving you a solid connection without the worry of leaks.

What’s more, this hose is UV and ozone resistant, so if you’re working on something that’s going to be exposed to the elements, you can trust it to hold up over time. Just keep in mind, it’s not compatible with fuel or oil, so don’t go trying to use it for those applications.

In terms of specs, you’re looking at a wall thickness of about 4.5mm (+/- 0.5mm), and each leg is 4 inches long, which gives you some flexibility in how you set things up. The blue color? It’s not just for looks; it stands out and can give your engine bay a clean, finished vibe.

Overall, if you’re in the market for a reliable silicone elbow coupler that can take the heat and keep performing, the HPS 90 Degree Elbow is worth considering. Trust me, you won’t regret having this in your toolkit.
