HPS 1-1/4" to 1-3/8" Silicone Reducer Coupler Hose

If you're diving into some serious automotive or marine projects, this HPS silicone reducer coupler hose is a solid choice. It's not just any hose; it’s built to handle the heat—literally. With a temperature range that goes from -65°F to a scorching 350°F, this thing is tough enough for high-performance setups. Whether you're working on custom turbo piping or need something reliable for your radiator cooling system, this hose has got your back.

Let’s talk specs. This hose measures between 1.25" and 1.38" internally (that’s 32mm to 35mm for you metric folks), and the outside diameter is around 1.65" to 1.75" (42mm to 45mm). At 3 inches long, it’s a good fit for various applications without being too bulky. The 4-ply reinforced design means it’s not going to buckle under pressure, which is key if you're pushing your rig to the limit.

One thing to keep in mind: this hose isn’t meant for fuel or oil. It’s made from high-temperature silicone that’s UV and ozone resistant, so it’ll hold up against the elements. Perfect for those who like to tinker with their setups or need something durable for industrial use.
