If you’re diving into some serious projects, you’ll want to check out this HPS 1/8" (3mm) Red high temp reinforced silicone heater hose. Now, I know what you might be thinking—it's just a hose, right? But this isn’t just any old rubber tube. This stuff is built to last and designed for the heavy-duty stuff. It meets and even exceeds SAEJ20 industry standards, so you know it’s up for the challenge, whether you’re using it for marine applications, custom turbo setups, or just trying to keep your radiator cooling system in check.
This silicone hose can handle some serious heat, with a temperature range that goes from -65°F to a blistering 350°F (that’s about 177°C for those who prefer metric). The heavy wall design means it can take on extreme pressure—up to 85 psi, to be exact. And if you’re worried about flexibility, don’t be. This hose is ultra-flexible with excellent tensile strength, making it easy to work with, even in tight spaces.
One of the real perks here is that it’s sold by the foot, and when you order, you’ll get it in one continuous roll. No more piecing together multiple sections. Just cut what you need and get to work. Just a heads up, though—this silicone hose isn’t compatible with fuel or oil, but it plays nice with water and anti-freeze, so it’s perfect for your cooling systems.
To break it down a bit more, here are some specs you might find helpful:
Plus, it’s UV and ozone resistant, so you don’t have to worry about it cracking or peeling over time. If you’re looking for a reliable hose that can handle the heat and pressure, this HPS silicone heater hose is definitely worth considering. It’s tough, flexible, and ready for whatever you throw at it.
