If you're diving into a project that demands some serious performance, let me tell you about the HPS 1-1/4" to 1-3/8" 90 Degree Elbow Reducer Coupler Hose. This isn’t just any silicone hose; it’s built tough with a 4-ply reinforced design that can handle the heat—literally. We're talking a temperature range that goes from a chilly -65°F all the way up to a scorching 350°F. That’s right, whether you're in a marine setting or customizing your turbo setup, this hose has got your back.
What I really appreciate about this hose is how it meets and exceeds SAEJ20 industry standards. That means you can trust it for heavy-duty pressure connections without breaking a sweat. I’ve used it for everything from DIY intake systems to radiator cooling setups, and it’s performed like a champ every time. The flexibility of this hose makes it a breeze to work with, and the 90-degree angle is perfect for tight spaces where you need a reliable connection.
Now, let’s talk specs. The inside diameter ranges from 1.25" to 1.38" (that’s 32mm to 35mm for those of you on the metric system), and the outside diameter is about 1.66" to 1.75". Each leg is 4 inches long, giving you plenty of room to work with. The wall thickness is a solid 4.5mm, which adds to its durability while keeping it lightweight.
Oh, and one more thing—this hose is UV and ozone resistant, so you won’t have to worry about it degrading under the sun or harsh conditions. Just keep in mind that it’s not compatible with fuel or oil, so save it for your cooling and intake projects.
In short, if you’re looking for a reliable, high-performance silicone hose that can handle the heat and pressure, this HPS elbow reducer is definitely worth considering. It’s rugged, versatile, and gets the job done without any fuss.
