If you're diving into a project that involves vacuum systems, you might want to take a good look at this HPS high-temperature silicone vacuum tubing. I've had my hands on this stuff, and it's become a go-to for everything from turbo setups to coolant systems. Seriously, if you’ve ever dealt with those stock rubber lines that turn brittle and crack after a while, you’ll appreciate the upgrade this silicone tubing offers.
One of the first things you'll notice is how flexible it is. The 1.5mm wall thickness makes it slimmer than the usual 3mm options out there, which is a game-changer when you're working in tight spots—like the vacuum ports on an RX-7 rotary engine. Trust me, that extra space can make a world of difference when you're elbow-deep in an engine bay.
This tubing is built to last. Unlike rubber, which can harden and fail over time, this silicone is tough enough to handle high temperatures and pressures. It’s rated for up to 350°F, so whether you’re working on a marine project or something for your daily driver, it’s got you covered. Plus, it’s resistant to UV and ozone, which is a nice touch if you’re planning to expose it to the elements.
Just a heads-up, though: this stuff isn’t compatible with fuel or oil, so keep that in mind when you’re planning your setup. But for vacuum advance systems and emission control, it’s spot on. You get 50 feet of this black beauty, with an inside diameter of 3.5mm, which is perfect for a variety of applications.
In short, if you’re tired of dealing with those flimsy rubber lines and want something that can handle the heat—literally—this HPS silicone vacuum hose might just be what you need.
