If you're diving into some serious DIY projects or just need a reliable coupler hose for your ride, the HPS 3/8" (9.5mm) x 3 Feet Long High Temp 4-ply Reinforced Blue Silicone Tube Coupler Hose is a solid choice. I’ve used a few of these on my own setups, and I can honestly say they’ve held up like champs. This hose is not just any silicone tube; it’s built to take a beating and keep on performing.
First off, let’s talk about the construction. This hose features a robust 4-ply design that’s engineered to handle heavy-duty pressure connections. It meets and even exceeds SAEJ20 industry standards, so you know it’s got the chops for high-temperature applications. I’ve pushed this thing in some pretty hot environments, and it’s never let me down. The temperature range is impressive, too—it's rated from -65°F to +350°F (that’s about -54°C to 177°C for the metric folks). If you’re running a custom turbo setup or need something for your intercooler piping, this is the hose you want.
Another thing I appreciate is its versatility. Whether you’re working on a marine project, an industrial application, or just a DIY intake or radiator cooling system, this hose fits the bill. Plus, it’s UV and ozone resistant, which means it won’t break down easily when exposed to the elements. Just keep in mind, this silicone hose isn’t compatible with fuel or oil, so save it for coolant and air applications.
Now, for the specs lovers out there, here’s the nitty-gritty: the inside diameter is 3/8" (9.5mm), while the outside diameter comes in at about 0.77" (19.5mm). With a wall thickness around 4.5mm (give or take), it’s sturdy enough to handle whatever you throw at it. And let’s not forget that striking blue color—it adds a nice touch to any engine bay.
So, if you’re in the market for a reliable, high-temp silicone hose, give this one a shot. It’s been a game-changer for my projects, and I’m sure it’ll serve you well too.
