Universal Oil Catch Can Baffled Reservoir Tank Air-Oil Separator, 2 Port Plug+Fittings+Filter, Aluminum, 150ml, Black

For 20 bucks, this is an amazing product. I remember a few years ago, that would get you a literal can with no fittings, no filter media, no drain valve, etc. That said, you might need to take a trip to autozone to get the tank to 100%, but for the price, it’s still worth it.I actually used this as an expansion tank to catch / drain my diff fluid as I drove the car around, so functionally, it’s a lot easier to deal with than a catch can. I did need to shave down some threads of the connector I screwed into the bottom to try to form a flat “floor.” Otherwise, there’d always be some level of fluid that wouldn’t be able to drain back into my diff after the car cools down.- loctite thread sealant: the drain valve on the bottom looks to be npt (designed to seal at the threads), dabbing some on before install would probably be a good idea to preempt any leaks.- top connectors seal with o rings that are provided. My use case doesn’t need it to be air tight, but if these leak, I’m guessing a crush washer would be an alternative. You can use thread sealant on this too, but the connector wasn’t designed to seal at the threads. Not sure how well this would work, though it sounds like some other reviewers used it to solve their issues.

The can is small so it can be mounted in lots of places. The port fittings are plastic but if you use a little Teflon tape you don't have to over tighten them to get a good seal. The valve on the bottom is very handy so you can run a piece of clear tubing down close to the frame, in my case right next to the oil filter so whenever I change oil I can drain the can.

Amazing. Simply amazing. I used this to replace a baffled catch can I've been using all this time. Everything in package came as described. Quality is great, filter is nice. Every few hundred miles, I use the valve to drain. Best oil catch can I've ever had.

Works very well

Love the product for the price, however I ordered two and one came 3/8” NPT like described and even answered by the company, and the other came metric straight thread with a textured finish versus gloss finish.

Great Quality is full performance.
