If you're diving into some serious engine work or just looking to upgrade your ride, this 90-degree HPS Performance silicone elbow coupler is a solid choice. It's not your average rubber hose—this bad boy is built tough, meeting and exceeding the SAEJ20 standards. That means it's ready to handle heavy-duty pressure connections without breaking a sweat.
One of the standout features is its heat resistance; it can take on temperatures up to 350°F (177°C). So whether you're pushing your engine or just dealing with the heat from a supercharger aftercooler, this silicone elbow has got your back. And let’s be honest, who wants to deal with the hassle of a rubber hose that can’t keep up? With a 4-ply reinforced design, this coupler is leagues ahead in durability compared to those flimsy rubber options you find at auto parts stores.
Installation? A breeze. Its flexibility means you can fit it into those tight spots in your engine bay without losing your cool. Plus, if you need to trim it down to replace an OEM or aftermarket rubber heater hose, you can do that easily. Just keep in mind, this elbow is meant for water or anti-freeze coolant—so no fuel or oil, please.
Whether you’re working on your car, a boat, or even an industrial setup, this silicone elbow is versatile enough to handle it all. With an inside diameter of 3/4" and leg lengths of 4" and 6", it’s designed to fit a variety of applications. And let’s not forget the sleek black color—it just looks good in any setup.
Here’s a quick rundown of the specs: the inside diameter is 19mm, and the outside diameter comes in at 1.12" (28mm). It also features a wall thickness of 5mm, which adds to its overall strength. So if you’re in the market for a reliable, high-performance silicone elbow coupler, this HPS option is definitely worth considering.
