Do You Have Replacement Access Plugs for a MORryde Pinbox?

Updated 03/30/2026 | Published 07/13/2025

Question:

I have a MORryde fifth-wheel hitch. Part no. RPB72-1621HD. GVWR 18,000 lbs. I need the rubber plugs which seal holes on the top of the hitch. Do you sell these?

No, I am sorry William we do not. I checked MORryde's website they don't list them either. I looked at the parts list breakdown for the MORryde Cushioned 5th Wheel Pin Box item # MR84VR. The part you're looking for is called a Access Plug and it's part number is UO136-181.

Hey William, did you manage to find the rubber plugs you were looking for? I'm curious because it could help others in a similar situation.

@JerredH. Anyone find info on this plug? This part must be difficult to find. Someone helped themselves to one of mine off of my brand new Solitude.
