If you're diving into some serious projects, whether it's a turbo setup or just upgrading your cooling system, this HPS 1-1/8" to 1-1/2" (28mm - 38mm) 4-ply Reinforced Blue Silicone Reducer Coupler Hose might just be your new best friend. I've used this hose for a while now, and it really holds up under pressure. Seriously, it meets and exceeds the SAEJ20 standards, which means you can trust it for those heavy-duty connections.

What I love about this hose is its resilience. It can handle temperatures from a chilly -65°F all the way up to a scorching +350°F (that’s about 177°C for those who prefer metrics). So, whether you're in a hot engine bay or dealing with high-pressure scenarios, this silicone reducer is built to last. The 4-ply construction gives it that extra toughness, making it perfect for marine and industrial applications, not to mention custom turbo or intercooler setups.

Now, let’s talk dimensions. The inside diameter ranges from 1.12" to 1.5" (that’s 28mm to 38mm), and the outside diameter sits between 1.5" and 1.89" (38mm to 48mm). It’s a solid 3" long with a wall thickness of about 4.5mm, so it’s got some heft to it. Plus, the blue color? It really pops under the hood or in your custom build.

Just a heads up, though—this silicone hose isn’t compatible with fuel or oil, so keep that in mind when planning your projects. But if you’re looking for something that’s UV and ozone resistant, this hose has got you covered. It’s ideal for DIY intake or radiator cooling systems, and it’s just a solid choice overall.

  • Reinforced Layer: 4-ply Polyester
