I tried this product for an aviation application. I own a DHC-2 Beaver aircraft that has a tail wheel axle that is 1.125 inch ID. I wanted an end cap that was removable because the axle tube is used to steer the aircraft with a hand held bar during some ground movement. So far the rubber cap seems to work. It has remained on during several flights. It is easy to remove and insert. The only problem may occur if the cap mounting area of the axle become oily or greasy which may allow the cap to slip off. It seems to need a friction fit to stay on.138273

Same as described above.

Not all my order was delivered. I ordered 4 sets of ez lube dust caps. They only sent 2 sets. Online the order tracker showed the order had been changed to 2 sets. So someone thought thats is what i needed, despite the order clearly being for 4. I've got multiple trailers these are used on and they go bad over time. The brakes are yet to be installed, but they look good out of the box.1313118

I will have our customer service team reach out to you. I do see that four of part # RG04-010
Grease Cap Plug for E-Z Lube Grease Caps - Qty 2
$4.33 were ordered which would mean that you would receive eight plugs in total.

I have always found etrailer excellent to work with. Not only do they offer a wide range of products, but personal interaction is available and always helpful. It is tragic that this is a thing today, but the availability of a live human being that actually gives a s$%t about your needs is increasingly rate. Etrailer still offers this and they should be recognized and rewarded for it in my opinion!1432385

Worked perfectly. Fit perfectly. Have held-up on a light trailer for multiple trips.1411924

Purchased bearing races, tapered roller bearings, seals and dust cap to have for spares for our 2012 Catalina Santara 281BHS travel trailer. Quality products .1409419

The product is exactly what I needed. I was most surprised with the speed that my grease caps were shipped. I ordered them and about an hour later I received and email showing that my items had shipped!1468003

Great replacement for my worn out plugs. Fast delivery1527810

Exactly same as original equipment. Great product and price.1165641

Due to high mileage use of trailer, the hubs are greased every 3 months. The caps are doing great.

Great product works as advertised. I would recommend.1545617

These are the caps that get removed to pump grease into an Ultra-lube hub. Perfect fit on my trailer with AL-KO 8490 axles and 10x2.25 brakes. Very nice price for a product that can be hard to find locally.
I can't prove it, but my research suggests these cross reference to:
+ 85-10
+ AL KO #568067
+ Hayes #09213611
+ TruRyde RG01-010

Fit fine , work good. 1543148

I've used eTrailer before and they've always had what I needed and my CSR - Ashley E. has been very helpful. Product is what I needed, shipping was on time, could not ask for better service1016511

They have started to leak some but I have found that you need to replace them on a yearly basis as they dry rot and crack...No problems tho after replacing them...

This is the second time I have ordered items from etrailer and am extremely pleased with the way sales staff assisted me then and now. The sales staff member assisting me with the order of grease cap plugs was Mariah A. She was great. I received my order as ordered on November 2nd,2020 and did the simple install right away on my ATV trailer. I will definitely do business with etrailer again. Thanks again Mariah A.907338

The grease plugs are performing as expected.I am very satisfied with this product.

I cannot honestly give these a good rating as I cleaned up my old ones and will be putting them back into service. While the rubber on these is soft and pliable compared to the original equipment, the tolerances are all wrong to be able to get a snug seal. The groove in the seal that fits over the sheet metal cap is too wide in the first place, something like 1/16" with the metal being probably half that. Second thing is the hole is slightly larger then the center of the rubber when it is installed meaning this plug does not make a tight seal, my old stiff ones make a tighter seal and will be reused. Also, the part of the rubber plug in the inside has a much smaller lip the catch the metal then the old ones which probably makes it easier to get off and put back on but also means it can fall off much easier as the tolerances are such that it moves around and does not seal tight. In my experience I cannot recommend these.475850

Nothing has changed, my opinion is still the same and they still sit in a parts bin unused solely to be used as backup in case of emergency.

I bought these against future need. I was taking the trailer on a long trip to from Tennessee to Minnesota and ending in Pennsylvania. Turned out I didn't need them (or the bearings bought for the same reason), but It was reassuring to have them.1308445

Perfect fit. Does what it is supposed to do. I put these on a 1988 Bass Tracker boat trailer. 553732
