If you're diving into a hard line project, let me tell you, the AN819-8 HPS Tube Sleeve is a solid choice. With its thin walls and tighter bend radius, it’s perfect for those tight spots where flexible hoses just won’t cut it. I’ve used it myself, and it really shines when you need to make the most of limited space without sacrificing performance.
Now, these fittings come in a sleek Type II anodized black finish, which not only looks good but also offers great abrasion and corrosion resistance. That means you can trust it to hold up under the harshest conditions, whether you’re dealing with fuel, oil, coolant, or even nitrous. Seriously, it’s versatile enough to handle just about anything you throw at it.
One thing to keep in mind is that the tubing and tube nut aren’t included, so you’ll want to grab those separately (look for part number AN8188). But once you’ve got everything, you can build your own hardlines as a reliable alternative to those flexible hoses that can wear out over time.
Here’s a quick rundown of what you’re getting:
In short, if you're looking to take your setup to the next level with some custom hard lines, the AN819-8 HPS Tube Sleeve is definitely worth considering. It’s a small piece that makes a big difference in performance and reliability.
