If you're diving into some serious DIY projects or just need a reliable hose for your setup, check out this HPS 1/2" (13mm) x 3 Feet High Temp Silicone Tube Coupler Hose. This isn't just any silicone hose; it's built tough with a 4-ply reinforced design that can handle the heat—literally. It’s rated for temperatures ranging from -65°F to a scorching +350°F (that’s about 177°C for the metric folks), making it a solid choice for high-temperature applications.
Whether you're working on custom turbo piping, intercooler setups, or even a DIY intake or radiator cooling system, this hose has got your back. It's perfect for heavy-duty pressure connections and meets SAEJ20 industry standards, so you know it’s built to last. Just keep in mind, this silicone hose isn’t compatible with fuel or oil, so save it for your cooling systems and air intakes.
One of the cool features is its UV and ozone resistance, which means it won't degrade easily when exposed to the elements. That’s a big plus if you're using it in marine or industrial environments. The inside diameter is 1/2" (13mm), and the outside diameter is 0.91" (23mm), giving you a snug fit for most applications. Plus, with a wall thickness of about 4.5mm, it's sturdy enough to handle whatever you throw at it.
So, if you’re looking for a hose that can take the heat and stand up to tough conditions, this HPS silicone tube coupler is a solid pick. At 3 feet long, it gives you plenty of length to work with, whether you're making connections or running lines. Just remember, it’s not for fuel or oil, but for everything else? It’s a champ.
