Selected User Reviews For National 4278 Differential Pinion Seal

Sealing job well done! I purchased the item as per my need

5/5

It fit perfectly and required little to no assembly. The job does not require a lot of mechanical skill, but a little would definitely be helpful. YouTube has many videos showing how to remove and install the mixer, so anybody who has basic hand tools should have no problem completing the task.

An official seal of quality

5/5

I give it five stars

5/5

Having a double lip seal of this quality is a real plus. The myriad of things to say are not many. The dimensions given in the listing seem to refer to something other than the seal, as I have no idea what they refer to.
