If you're diving into some serious engine work or just looking to upgrade your cooling system, let me tell you about this HPS 1/2" (13mm) x 3 Feet Long High Temp Silicone Tube Coupler Hose. This isn’t just any hose; it's built tough with a 4-ply aramid reinforcement that can handle the heat. We’re talking a max temperature rating of 500°F, so whether you're fabricating custom turbo piping or just need something reliable for your radiator, this hose has you covered.
One of the things I really appreciate about this hose is that it meets and exceeds SAEJ20 industry standards. That means it's not just good for your average DIY project; it's designed for heavy-duty pressure connections. So, if you're working on something marine or industrial, or maybe just a high-performance ride, you can trust this silicone hose to hold up under pressure.
Now, let’s get into the nitty-gritty. The inside diameter is a solid 1/2" (13mm), and it has an outside diameter of 0.91" (23mm). The wall thickness is around 4.5mm, which gives it that extra durability without being overly bulky. And hey, it comes in a bright orange color that not only looks cool but is also UV and ozone resistant—perfect for those sunny days when you’re out showing off your ride.
Just a heads-up, though: this silicone hose isn’t compatible with fuel or oil, so keep that in mind when planning your setup. But for coolant, intake, or intercooler applications, it’s a solid choice. Plus, at 3 feet long, you've got a decent amount of hose to work with, whether you’re doing some intricate piping or just need a reliable connection.
In short, if you're looking to upgrade your cooling system or tackle a custom project, this HPS silicone tube is definitely worth considering. It's built to last, performs well under heat, and gives you the peace of mind that comes with quality engineering.
