If you’re looking for a solid way to connect different-sized pipes, the HPS 2" to 3" Silicone Reducer Coupler Hose in black is a game changer. This isn’t just any hose; it’s built tough with a 4-ply reinforced design that can handle some serious heat. We’re talking about a temperature range from a chilly -65°F all the way up to a scorching +350°F, so you know it’s ready for whatever you throw at it.
What I really appreciate about this hose is its versatility. It’s perfect for transitioning between intercoolers, turbos, and intake components. If you’re into high-performance racing or just need something reliable for your truck or agricultural equipment, this hose has got you covered. Plus, it’s made from high-quality silicone rubber that meets or exceeds the SAEJ20 standard, so you can trust it to hold up under pressure.
With an inside diameter that expands from 51mm to 76mm, and an outside diameter of 2.40" to 3.39", this hose fits snugly where you need it. The wall thickness is a solid 5mm, giving it that extra durability. And at 3 inches long, it’s just the right size for most applications without being cumbersome.
Just a heads up, though—this silicone hose is not compatible with fuel or oil, but it works great with water and coolants. Whether you’re a pro in the racing scene or just a DIY enthusiast, this reducer coupler is a practical addition to your setup.
