Alright, let’s talk about this HPS 3" to 3-1/4" silicone reducer coupler hose. If you're diving into some serious DIY projects, whether it's for your turbo setup or just spicing up your cooling system, this piece of silicone is a solid choice. It’s 6 inches long and built tough with a 4-ply reinforced design, so you know it can handle the heat—literally. We’re talking a temperature range of -65°F to +350°F, which means it can take a beating without breaking a sweat.

Now, I’ve seen a lot of hoses out there, but this one stands out because it meets and exceeds SAEJ20 standards. That’s big for anyone who’s serious about their builds. You can trust it for heavy-duty pressure connections, whether you’re working on marine applications or just trying to get that custom intercooler piping just right. Just keep in mind, this silicone isn’t fuel or oil-resistant, so save it for your coolant and air intake setups.

Let’s get into the nitty-gritty specs. The inside diameter ranges from 3" to 3.25" (76mm to 83mm), and the outside diameter is about 3.39" to 3.66" (86mm to 93mm). The wall thickness is around 4.5mm, which gives it that extra durability you want when things heat up. Plus, it’s UV and ozone resistant, so you don’t have to worry about it degrading over time if it’s exposed to the elements.

In short, if you’re after a reliable coupler hose that won’t let you down, this HPS option is a great pick. It’s built for performance and can handle whatever you throw at it. Just make sure you’re not trying to run fuel through it, and you’ll be golden.
