If you’re looking to connect your silicone or rubber hoses without the worry of leaks, the HPS Billet Aluminum Hose Union is where it’s at. I’ve used this little gem on my own projects, and let me tell you, it’s a game changer. Crafted from 6061 grade aluminum, this adapter fitting is not just lightweight but incredibly durable too. Whether you’re routing coolant, air, or even fuel, this thing holds up like a champ.
What I really appreciate is the multi-ribbed design. It ensures a tight, leakproof seal every time. No more guessing if you’ve got a solid connection. The center stopper is a nice touch, too—it helps align the hoses perfectly, so you can get a clean fit without any hassle. Plus, its compact size makes it ideal for those tight spots or tricky back-to-back bends that can be a real pain to work with.
Here’s the nitty-gritty: it has an outside diameter of 1 1/8 inches (or about 28mm), with a wall thickness of 2mm, and an overall length of 2 inches. The anodized silver finish looks sharp and adds a bit of flair to your setup. This isn’t just some run-of-the-mill connector; it’s a solid piece of hardware that I trust for my builds.
So, if you’re in the market for a reliable hose union, consider giving the HPS Silver 1-1/8 inch Billet 6061 Aluminum Joiner a shot. It’s one of those parts that you’ll appreciate having in your arsenal, especially when you’re knee-deep in a project and need things to go smoothly.
