If you're diving into some serious engine work or custom builds, let me tell you about this HPS 3" - 5" Silicone Reducer Coupler Hose. It’s not just another piece of rubber; this thing is built to last and handle some heat. With a 4-ply reinforced design, it meets and even exceeds SAEJ20 standards, making it perfect for heavy-duty pressure connections.

Whether you're fabricating a turbo setup or piecing together an intercooler system, this hose has got your back. It’s versatile enough for marine and industrial applications, so you can really put it to the test. The temperature range is impressive too—this hose can handle anything from -65°F to a scorching 350°F (that’s about 177°C for those who prefer metric). So, if you’re pushing your setup to the limits, you won’t have to worry about this coupler giving out on you.

Now, let’s talk dimensions. The inside diameter spans from 3" to 5" (or 76mm to 127mm), which gives you some flexibility when it comes to fitting your needs. The outside diameter ranges from 3.39" to 5.39" (86mm to 137mm), and with a solid wall thickness of around 4.5mm, this hose is built tough. Just keep in mind, it’s not compatible with fuel or oil, so plan your setup accordingly.

One of the standout features is its UV and ozone resistance, which is a big plus if you're using it in outdoor applications. You want your gear to last, right? And this hose, with its sleek black finish, not only performs well but looks good doing it.

  • High Temperature 4-ply Reinforced Silicone
  • Meets SAEJ20 standards for heavy-duty connections
  • Ideal for marine, industrial, and custom piping projects
  • UV and ozone resistant for outdoor durability
  • Not compatible with fuel or oil

So, if you're in the market for a reliable, tough silicone reducer coupler hose, the HPS 3" - 5" ID option is worth a look. It’s designed for those who know what they need and won’t settle for less. Get ready to take your project to the next level!
