Grease cap fits trailer hubs with 1.988" inner diameter and has corrosion-resistant zinc plating.


I Installed two sets on my 14 foot Trailer. In the mountains of NC, brakes dont seem to last on the truck. I use the truck and trailer for pick up and delivery of Ventracs, that weigh in at around 1500LBS. The trailer empty will actually stop the truck now. (I use the Redarc trailer brake controller).
Not having to constantly adjust them is a major plus also. I did wire both axles indepentanly of each other to the junction box. If I happen to have a wire get torn loose, I will only lose braking on one axle and not both.
They were a little expensive, but will save me from replacing the brakes on my truck twice a year.
Over all, I am glad I got the two sets.

Trailer gets very little use, caps work as they should.


I love etrailer!


Standard dust covers to replace bent on es


The grease caps were available on The ordering was simple and easy. They arrived earlier than expected and exactly as we wanted. They work on our trailer. We would order from again.


I ordered 3 Taskmaster 4.80-12 Bias Trailer Tire with 12" White Mod Wheel - 4 on 4 - Load Range C (Item # TTWAS12B4WMHP) on a Saturday. To my surprise they shipped them right away. The packaging was perfect and the wheels look strong and well made. This little kit trailer (cargo box is 60"x40"x24") has once been in a 3000 mile trip around the West, and the 8" wheels where almost 20 years old so I decided to get fresh tires and ordered the 12" wheels. I'll probably have to give the fenders a little more clearance but that's OK. I'm very happy with the product and service. Thank you guys!


always have the parts I need, fast serv ice


It all started about 10 years ago when I purchased a custom built trailer. The trailer is great, but one of the stub axle/wheel kits they put on was missing a race. By the time I got the trailer home -- about 7 miles -- the dust cap was missing. Later I pulled off the wheel and noticed the race was gone and I replaced it and the bearing. I purchased several dust caps locally, all of which were supposed to fit. None of the ones off my old vehicles would work. After losing several more caps, I ordered these. Thinking I would lose them fairly quick, I ordered extras. When the box arrived, I examined the caps and was pleased with the quality. I took the beer can off the wheel and carefully hammered a new cap on. Well, now after pulling the trailer a lot, on many bumpy and bad roads, this cap has not loosened a bit. I highly recommend these caps.

These caps are still on my trailer after many more miles of bumpy roads and pulling through pastures with high weeds and brush. Still very pleased.

Like the fact that everything comes greased and ready for immediate installation. Perfect replacement!


the cap was machined slightly larger diameter then the one that it replaced. It was difficult to install but with some modification it is doing the job.


It fit snug and is keeping the water out


Couldn't be happier !!

I went to
{online store] and took old one in with me, they had to order it in and $XX.00 freight to boot. It showed up wrong and they wouldn't credit the freight back.

I went online and order here and no problems and received sooner than expected.

Top customer service and yes, now marked in my favorites for future use.

I measured the hub and order the grease cap. It was installed using a piece of PVC pipe and a dead blow hammer and it sealed tight and looks great.

Great quality products and very fast service! Thank You!


These came with a bearing kit I ordered for my trailer and they don't fit. My trailer dates back to the 60;s and the hubs are cast aluminum and, apparently almost impossible to find parts for.


Great service. The parts were here in two days. Best part they were less than half the price even with shipping than the local auto stores and big box retailers were asking for.


Thank you so much for replacing the damaged components in such a timely manner! The grease caps have been installed and the boat is in the water. I have been using etrailer for quite a while and have never been disappointed. This is my "go to" vendor for all of my trailer/towing issues.


Nice tight fit. Easily installed with Dust Cap Driver Tool #290-991. I may be possible to install these undented without it, but the driver tool made it a very quick job.


All the products were exactly what I needed to repair my trailer. After a little glitch in the order I contacted customer service and the problem was immediately resolved. I will definitely be shopping again when/if I need parts.


Good value. A little tighter fitting than original ones on Dexter 2,200lb axle, so a bit tough to install. Plain silver steel, no markings on them, fine by me. I wish they were a bit beefier, but that's how it goes these days.


This is a fine grease cap. It slightly too large to fit my Quality Trailer Products Accu-Lube 3500# hubs, however, that is not the fault of e-trailer.


They fit my hubs and keep the grease in for a good price. Not much else to say. I did go to the hardware store and get a pipe fitting to drive them in so I didn't dent them during installation.


The cap fits my trailer. Keeps the grease in and dirt out. It's a cap, what more can I say.


Every item I ordered worked and fit exactly as I had hoped it would. Prices and shipping was top notch and will definitely buy from e-trailer again.


It Was Great. It Got Here Before I Ordered It. Perfect Fit.
