So, you’re looking to upgrade your setup? Let me tell you about this HPS High Temp Silicone Reducer Coupler Hose. It’s not just any hose; it’s built tough with a 4-ply reinforced design that really stands up to the heat. We’re talking about a temperature range from a chilly -65°F all the way up to a scorching 350°F. That’s right, whether you’re pushing your engine to the limit or just cruising around, this hose can handle it.
Now, if you’re into custom builds—like turbo or intercooler piping—this is where it shines. The inside diameter ranges from 2 inches to 2-1/4 inches (51mm to 57mm), and it fits snugly with an outside diameter between 2.40 inches and 2.64 inches (61mm to 67mm). Plus, it’s a solid 4 inches long, so you’ve got plenty of room to work with. Just a heads-up though: it’s not compatible with fuel or oil, so keep that in mind when you’re planning your setup.
This hose isn’t just for car enthusiasts; it’s also great for marine and industrial applications. It meets and exceeds SAEJ20 standards, which is a big deal if you care about quality and durability. And if you’re worried about UV and ozone damage, don’t be—this hose is resistant to both, so it’ll hold up over time.
In a nutshell, if you want a reliable, high-performance silicone hose that can take the heat and keep your connections secure, this HPS reducer coupler is a solid choice. Just remember to check your fitment and enjoy the peace of mind that comes with using quality parts.
