If you’re diving into some serious automotive work or just need a reliable hose for your project, the HPS Performance 5/16" FKM lined silicone hose is worth a look. This thing is built to handle a lot of the nastier stuff you might encounter—think acids, oils, and a whole bunch of chemicals that would make lesser hoses cringe. The FKM lining is a game changer; it’s a fluoroelastomer that doesn’t just sit pretty. It can take the heat—up to 350°F, to be exact—without losing its cool or its structural integrity.
What I really appreciate about this hose is its flexibility. With a 5/16" inside diameter (that’s about 8mm for those who prefer metric), it fits snugly into various applications. Whether you’re routing fuel return lines, managing crankcase ventilation, or setting up turbo oil returns, this hose has got you covered. Just keep in mind, it’s not meant for continuous alcohol fuel flow or situations where it’s submerged in fuel. So, if you’re working on a project that fits those parameters, you might want to look elsewhere.
The construction is solid, too. It’s reinforced with a single layer of polyester, which gives it that extra tensile strength you want when you’re dealing with high-pressure situations. The wall thickness is a sturdy 4mm, so you know it’s not going to buckle under pressure. And while it’s not oil-resistant, its ability to withstand ozone and various synthetic hydraulic fluids makes it a versatile choice for many setups.
To put it all together, this hose measures 6 feet in length and has an outside diameter of about 0.62" (16mm). The black color gives it a sleek look, which is always a bonus when you’re trying to keep things tidy under the hood. If you’re serious about your automotive projects, you’ll want to give this hose a shot. It’s reliable, flexible, and ready to take on whatever you throw at it.
