Question:

I’m converting reliable oil bath hub to grease and need a threaded cap. Reliable says it is 2 1/16”. Do you have something that will fit ?

Hello Jim,

Since your hub is measuring 2 1/16", I recommend using the Bearing Buddy Bearing Protectors - Model 2080T-SS - Threaded - Stainless Steel (Pair) # BB2080T-SS. It is a great maintenance free option. Don't forget some LubriMatic Prime Guard High Temperature Wheel Bearing Grease - Red - 16-oz Can # L11380 to complete the swap.

What kind of trailer is this going on?
