If you're diving into some serious custom work or just need a reliable hose that can take the heat, check out the HPS 1" - 1-3/8" High Temp 4-ply Reinforced Silicone 90 Degree Elbow Reducer Coupler Hose. This isn't just any hose; it's built to meet and even exceed the SAEJ20 industry standards, which means you can trust it for heavy-duty pressure connections without breaking a sweat.
I've used this hose in a few projects, and let me tell you, it really shines in high-temperature settings. Whether you're fabricating custom turbo setups or working on your DIY intake or radiator cooling system, this hose holds up like a champ. The temperature range is impressive too, from a chilly -65°F all the way up to a scorching 350°F (that's about 177°C for those of you who prefer metric). So, no matter what you're throwing at it, this hose can handle it.
One of the standout features is its 4-ply construction, which gives it that extra toughness. The inside diameter ranges from 1" to 1-3/8" (25mm to 35mm), while the outside diameter spans from 1.38" to 1.75" (35mm to 45mm). Each leg is 4" long, and the wall thickness is around 4.5mm, which is pretty solid for a silicone hose. Plus, it’s UV and ozone resistant, so if you're using it in a marine or industrial environment, you won’t have to worry about it degrading too quickly.
Just a heads up, though—this silicone hose isn’t compatible with fuel or oil, so keep that in mind when planning your setup. It’s available in a vibrant blue color that not only looks good but also stands out in your engine bay or custom build.
In short, if you're looking for a dependable, high-performance hose that can take the heat and handle some serious pressure, the HPS 90 Degree Elbow Reducer is a solid choice. It’s built for those who demand quality and performance, whether you're a weekend warrior or a seasoned pro.
