HPS 5" - 5.5" High Temp Silicone Reducer Coupler Hose

If you’re diving into some serious performance work or just need a reliable hose for your custom setups, this HPS 5" to 5.5" silicone reducer coupler is a solid choice. Made from high-temp, 4-ply reinforced silicone, it’s built to handle the heat—literally. With a temperature range from -65°F to +350°F, you can trust it to keep your connections tight and leak-free even under pressure.

What’s cool about this hose is its versatility. Whether you’re fabricating turbo or intercooler piping, or tweaking your DIY intake or radiator cooling system, it’s got your back. The inside diameter ranges from 5" to 5.5" (127mm to 140mm), which means it’s perfect for those larger setups. Just a heads up, the outside diameter sits between 5.39" and 5.9" (137mm to 150mm), so make sure you’ve got the right clamps to match.

One thing I really appreciate is the 4-ply construction. It adds that extra layer of durability, making it ideal for heavy-duty pressure connections. Plus, it’s UV and ozone resistant, so you don’t have to worry about it degrading over time if it’s exposed to the elements.

Just keep in mind, this silicone hose isn’t for fuel or oil applications. It’s designed for air and water, so plan your setup accordingly. If you’re looking for a hose that meets SAEJ20 standards and won’t let you down, this one’s worth considering.
