$23.22

Hey there, fellow gearheads! If you're diving into some serious performance upgrades or just need a reliable silicone hose for your setup, let me tell you about this HPS black silicone reducer coupler hose. It's not just any hose; it's built to handle the heat and pressure that come with high-performance applications.

This bad boy has an inside diameter that ranges from 1-3/8" to 1-7/8" (that’s 35mm to 48mm for you metric fans) and measures a solid 3 inches in length. With a maximum working pressure of 100 psi, it’s ready to tackle whatever you throw at it. And don’t worry about it melting down on you; it can handle temperatures from a chilly -65°F all the way up to a scorching 350°F (177°C). That’s some serious heat resistance!

The wall thickness is a beefy 4.5mm, so you know it’s tough. Just keep in mind, this hose is not compatible with fuel or oil, but it plays nice with air, water, and antifreeze—perfect for your cooling systems and intercooler piping. Whether you’re into turbo diesel pickups, custom builds, or heavy-duty machinery, this hose meets and exceeds the SAEJ20 standards, so you can trust it to perform under pressure.

Oh, and if you’re worried about UV or ozone exposure, don’t be. This silicone hose is resistant to both, making it a solid choice for just about any environment. Plus, HPS backs it with a limited lifetime warranty, so you can feel good about your investment.
