When it comes to tackling those tough automotive projects, having the right hose can make all the difference. The HPS 3/8" High Temp Red Silicone Vacuum Tubing is a solid choice for anyone who’s serious about their ride. Whether you’re working on vacuum advance systems, turbo setups, or even coolant lines, this hose has got your back.
What sets this tubing apart? For starters, it’s made from premium-grade silicone, which means it’s built to last. The heavy wall design isn’t just for show; it can handle extreme pressure without breaking a sweat. I’ve used it in high-stress environments, and it’s held up like a champ. Plus, it’s ultra-flexible, which is a lifesaver when you’re trying to fit it into tight spaces.
Let’s talk specs for a moment. This hose can handle temperatures from a chilly -65°F all the way up to a scorching 350°F (that’s about 177°C for those who prefer metric). With an inside diameter of 3/8" (or 9.5mm), it’s perfect for a variety of applications. The outside diameter is 0.62" (15.5mm), and you get a generous length of 50 feet, so you won’t run out mid-project. The wall thickness is a sturdy 3mm, providing that extra durability you want.
One thing to keep in mind is that while this silicone hose is tough, it’s not compatible with fuel or oil—so save it for vacuum and coolant systems. It’s also UV and ozone resistant, which is a big plus if your setup sees a lot of sun.
In short, if you’re looking for a reliable, high-temp silicone hose that won’t let you down, the HPS 3/8" High Temp Red Silicone Vacuum Tubing is worth considering. It meets and exceeds SAEJ20 industry standards, making it ideal for heavy-duty pressure connections. Whether you're into marine applications, custom turbo piping, or just need a solid DIY intake or radiator cooling system, this hose can handle it all.
