HPS Performance Products 5/8 Inch (16mm) 4-Ply Reinforced Black Silicone Hump Coupler Hose 6 Inch Length
$23.68

If you’re looking to upgrade your setup, this HPS 5/8" (16mm) Silicone Hump Coupler Hose is a solid choice. I’ve put this thing through its paces, and it really holds up under pressure. With a length of 6 inches and a 4-ply reinforced design, it’s built to take on high temperatures—up to 350°F (that’s about 177°C for those who prefer metrics). Whether you're tackling a custom turbo project or just need a reliable coupler for your DIY intake or radiator cooling system, this hose has got your back.

What I really appreciate about this coupler is its ability to handle misalignment and vibrations. If you’ve ever dealt with a setup that just doesn't want to line up right, you know how frustrating that can be. This hose compensates for those little quirks, making installation a breeze. Plus, it’s UV and ozone resistant, so you don’t have to worry about it deteriorating over time, especially if you’re using it in a marine or industrial application.

Just a heads-up though: this silicone hose isn’t compatible with fuel or oil, so keep that in mind when planning your project. The inside diameter is 5/8" (16mm), and the outside diameter measures in at about 1.03" (26mm). With a wall thickness of 4.5mm, it’s sturdy enough for heavy-duty connections while still being flexible enough to work with various setups.
