If you're diving into some serious custom builds or just need a reliable hose for your setup, the HPS 1/4" ID silicone 45-degree elbow coupler hose is worth a look. This isn't just any hose; it's built tough with a 4-ply reinforced design that can handle some serious heat—up to 350°F, to be exact. Whether you’re working on a marine project, industrial equipment, or even a custom turbo setup, this hose has got your back.
With a 10" leg length on each side, it gives you plenty of room to work with, making it perfect for those tricky angles in your piping. The inside diameter is 1/4" (or 6.5mm), and the outside diameter measures in at 0.65" (16.5mm). So, you know it’s not just sturdy but also fits well with standard connections. Plus, it’s UV and ozone resistant, which is a nice touch if you’re planning to use it outdoors.
Now, a quick heads-up: this silicone hose isn’t meant for fuel or oil, so keep that in mind when planning your setup. If you want to make sure it stays put, I’d recommend pairing it with the HPS embossed hose clamp (part number EMSC-10-16). Trust me, you don’t want any surprises when you’re out on the water or pushing your engine to its limits.
In short, if you’re looking for a reliable, high-performance hose that can take the heat—literally—this HPS 45-degree elbow coupler hose is a solid choice. It meets and exceeds SAEJ20 industry standards, so you know you’re getting quality that’s built to last.
