If you’re diving into the world of custom builds or just need a reliable coupler hose, this HPS 2-3/4" (70mm) x 3 Feet Long High Temp 4-ply Aramid Reinforced Silicone Tube Coupler Hose is worth a look. I’ve used my fair share of hoses, and let me tell you, this one’s built to last. It’s not just about looks—though that bright orange definitely stands out under the hood; it’s about performance and durability.

This hose is engineered to handle some serious heat, with a max temperature rating of 500°F. That’s a big deal if you’re pushing your engine hard or working on a custom turbo setup. It meets and exceeds SAEJ20 standards, which means it’s ready for heavy-duty pressure connections without breaking a sweat. I’ve used it for everything from DIY intake systems to radiator cooling setups, and it’s held up beautifully.

Now, let’s talk specifics. The inside diameter is 2.75" (70mm), and it has a solid wall thickness of around 4.5mm. The outside diameter is 3.12" (80mm), making it a snug fit for most applications. Just keep in mind, this silicone hose isn’t compatible with fuel or oil, so save it for your coolant and air applications.

One of the standout features is the 4-ply aramid reinforcement. This adds a layer of toughness that you just won’t find in standard hoses. Plus, it’s UV and ozone resistant, so it can handle the elements if you’re using it in a marine environment or just want it to last longer under the sun.

In short, if you're looking for a reliable, high-temp coupler hose that can take the heat, this HPS silicone tube is a solid choice. Just make sure it fits your project right, and you’re good to go!
