Hello, neighbors, Steven here with etrailer.com. Today, we're looking at our Dexter Fortress Threaded Aluminum Oil Cap for 10,000 to 16,000 pound axles. Now, folks, this does replace the oil cap, O-ring, and plug for these Dexter, Rockwell, Valcrum, and AL-KO axles. I'll put those numbers on the screen, so you have them available to you. Now, starting off, this nice red retainer ring, that's gotta protect the viewing glass there behind it. And then you got this nice rubber plug in the center, that's kinda common on these oil bath caps.
But now, with the aluminum ones, they got this threaded plug here where you can easily fill or even drain the oil, and you got the nice threaded outer part with that O-ring in there. Now, this cap can function technically as a grease cap, but predominantly, it is designed and manufactured pretty much as an oil bath cap. And traditionally, you see these as plastic, but again, this is aluminum, so a very nice upgrade for you. It's gonna thread on super easy, give you a nice elegant look on the hubs as well. Again, rated for 10,000 to 16,000 pound axles.
It's got a 3.75 inch overall diameter, a very nice five-year warranty. And I'll even toss up an expanded view on the screen here, so you can kinda see all the internal parts and whatnot, so very simple design. You have very robust, great functioning, great addition to your trailer hubs. Folks, that's gonna wrap it up for our look at this Threaded Aluminum Oil Cap by Dexter, 10,000 pounds to 16,000 pound axles. I'm Steven, stay safe out there.
