If you're diving into a custom build or just need a reliable weld bung, the HPS Aluminum AN-4 Weld Bung is worth a look. These bungs are crafted from 6061 aluminum, which is a solid choice for anyone who values strength without the extra weight. I’ve used these on a few projects, and they really hold up well under pressure.
What I appreciate about these weld bungs is their compatibility with 37-degree AN flare fittings. It makes the whole process smoother, especially when you’re trying to get everything lined up just right. Speaking of alignment, the back of the bung has this raised feature that keeps it steady while you're welding—definitely a game-changer if you've ever struggled with keeping things in place.
These bungs come in a raw, uncoated finish, which might not be the prettiest out of the box, but it saves you a ton of prep work. You can just get right into your project without worrying about any extra coatings getting in the way. Whether you're fabricating an oil catch can, a swirl pot, or even a custom fuel cell, these bungs fit the bill.
And let’s talk versatility. They’re compatible with just about everything—water, coolant, oil, hydraulic fluid, and even most fuels. So, whether you’re working on a daily driver or a weekend warrior, you can trust these bungs to handle whatever you throw at them.
In terms of specs, you're looking at a size of AN-4, which is perfect for a range of applications. The 7104AL HPS Performance Weld-on AN flare bung is really designed for those who are serious about their custom fabrication projects. So if you’re ready to take your build to the next level, this is a solid component to include.
