They were exactly what I needed, reasonably priced and showed up fast.

These are perfect for trailer bearings especially on brake axles because they lessen the chance of not over pressurizing the assembly. Fill slowly with pump style grease gun and stop at the first sign of grease coming out of the vent. I have seen some OTHER Spring type systems blow the back axle seals and allow grease to enter the brakes. I'm using these on both axles of my boat trailer that has rear axle electric brakes. I threw away a set of the OTHER spring type grease system.

Nice Quality for the price. Little tight going on but nice tight fit. Be careful not to touch the plastic vent opposite the grease fitting. They are pressed together with a spring and will come apart.

It is very tight fit,i had to retro fit them a little. I sanded them down on the edge a little to get them to fit. I used a 16oz. rubber mallet and they went right on. so far so good they working ok. And they are the right size for my trailer.But they needed some work.

Nice tight fit, requires a rubber mallet or deadblow hammer to install, as all hub bearing caps do.They take quite a bit of grease to fill initially, but after that first fill, it doesn't take too much to get new grease into the bearing.These are on a travel trailer, so the bearings don't see the harsh environments a boat or PWC might, but all was well on my 8,500 mile 3 week trip through some pretty crazy terrain and hours of washboard gravel roads.
