HPS Performance Products 1-1/8" (28mm) 4-Ply Reinforced Black Silicone 45 Degree Elbow Hose - HTSEC45-112-BLK

If you're diving into some serious DIY projects or just need a reliable hose for your high-performance setup, the HPS 1-1/8" (28mm) High Temp 4-ply Reinforced Silicone 45 Degree Elbow Coupler Hose is worth a look. I’ve used this hose for various applications, and it’s held up like a champ. The first thing you’ll notice is its robust build—this isn’t your average hose. It’s made from high-temperature, 4-ply reinforced silicone, so you know it can take the heat, literally. We're talking about a temperature range that goes from a chilly -65°F all the way up to a scorching 350°F (177°C). That's some serious versatility right there.

This elbow coupler is perfect for heavy-duty pressure connections, and it really shines in high-temperature applications. Whether you're working on a custom turbo setup, fabricating intercooler piping, or even tackling a DIY intake or radiator cooling system, this hose has got your back. I’ve found it to be especially useful in marine and industrial environments where reliability is key.

Now, let’s talk specs. The inside diameter measures 1.12" (28mm), which fits nicely into a lot of setups, while the outside diameter is 1.5" (38mm). Each leg is about 4 inches long, giving you enough length to work with in tight spaces. The wall thickness sits at a solid 4.5mm (+/- 0.5mm), providing that extra durability you want when pushing your engine to its limits.

One thing to keep in mind is that while this hose is UV and ozone resistant—great for those long days in the sun—it’s not compatible with fuel or oil, so plan your setup accordingly. Overall, if you’re in the market for a tough, reliable silicone hose that meets SAEJ20 industry standards, this HPS elbow coupler is a solid choice. It’s a no-nonsense part that gets the job done without any fuss.
