If you’re diving into some serious plumbing work on your ride, you’ll want to check out the HPS AN9251 Tee Adapter. This little piece of gear is a game-changer for connecting three hoses or tubes with 37-degree flares. Whether you're merging coolant lines or splitting fuel feeds, this adapter makes it easy to get the job done right.
What I really appreciate about this adapter is its thoughtful design. It features two male AN fittings on the run and a female AN fitting on the side, which gives you flexibility in how you set things up. It’s sized at AN-10, so it fits right into your existing setup without any fuss. Made from forged 6061 aluminum, it’s tough enough to handle whatever you throw at it—water, oil, coolant, or even nitrous. Plus, it's got that Type II anodized black finish that not only looks sleek but also provides solid abrasion and corrosion resistance.
When you’re working on your vehicle, you want components that can take a beating and keep on performing. This Tee adapter checks all those boxes. It’s compatible with a range of fluids, so whether you’re dealing with fuel, hydraulic fluid, or even alcohol, you can trust it to hold up. It’s a reliable choice for anyone who’s serious about their setup.
Here’s a quick rundown of the specs: it’s black, made from aluminum, and has three AN-10 ends. The angle is a straightforward 0 degrees, making it simple to fit into tight spots. Overall, if you’re looking for a solid, well-built Tee adapter that won’t let you down, the HPS AN9251 is worth considering.
