If you're diving into some serious DIY projects or need something reliable for your high-performance setup, check out this HPS 3/8" (9.5mm) x 1 Foot Long 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 some serious heat—up to 350°F (177°C) to be exact. So, whether you’re working on your turbo piping or need a solid connection for your radiator cooling system, this hose has got your back.

What I love about this coupler is that it meets and exceeds SAEJ20 industry standards, which means it's made for heavy-duty pressure connections. You can use it in marine setups or industrial applications without worrying about it failing on you. Just keep in mind, it's not compatible with fuel or oil, so save that for your fuel lines.

Here’s the nitty-gritty: the inside diameter is 3/8" (9.5mm), and the outside diameter measures 0.77" (19.5mm). It’s a foot long, which gives you some flexibility in how you use it. The wall thickness is around 4.5mm, providing that extra durability you want when things heat up. Plus, it’s UV and ozone resistant, so it can take a beating from the elements if you're using it in an exposed area.

  • High-temperature 4-ply reinforced silicone construction.
  • Perfect for custom turbo or intercooler piping, DIY intake, or radiator cooling systems.
  • Built to last with excellent resistance to high temperatures.
  • UV and ozone resistant for outdoor applications.
  • Remember, this hose isn’t for fuel or oil—stick to coolant and air!

So, if you’re looking to upgrade your setup or need a reliable hose for your next project, this HPS silicone tube coupler hose is worth considering. It’s solid, it’s dependable, and it’ll get the job done right.
