If you're in the market for a reliable silicone elbow coupler, let me tell you about this 90-degree HPS Performance piece. It’s not just any coupler; it’s built tough with a 4-ply silicone design that really stands up to the heat—up to 350°F (177°C), to be exact. That’s perfect for those high-pressure connections where you need something that won’t let you down.
Now, I’ve seen my fair share of rubber hoses that just can’t cut it, especially when things heat up under the hood. This HPS silicone elbow is a game-changer. It's engineered to handle the demands of high-performance applications, whether you're working on your car, a boat, or even some industrial setups. And if you need to replace an OEM or aftermarket rubber heater hose, this coupler can be easily trimmed to fit your needs. It’s flexible enough to make installation a breeze, even in those tight spots that seem impossible to reach.
One thing to keep in mind, though: this coupler is not compatible with fuel or oil. But if you’re dealing with water or antifreeze, you’re in the clear. The inside diameter measures 5/8 inches (16mm), with leg lengths of 5 inches and 18 inches, plus a centerline radius of 1 inch. It’s designed to last longer than those flimsy rubber hoses, so you can trust it to keep your system running smoothly.
In terms of specs, you’re looking at a solid piece with a wall thickness of 5mm and an outside diameter of 1 inch (25mm). The 4-ply polyester reinforcement really gives it that extra durability, and the black color means it’ll blend in nicely under the hood.
So if you’re ready to upgrade your setup and ditch those weak rubber hoses, this HPS silicone elbow is worth considering. It’s tough, reliable, and ready to handle whatever you throw at it.
