This is the hose cuff that attaches to the hose from the recovery tank to the blade on a NUC244/NUC440.
If your cuff is stuck on a old hose or is missing then this replacement could be just what you need to get the machine back up and running again.
This will fit the following models:
NUC244NX, NUC244NX-R, NUC244NX-RHM, NUC440, NUC440HM.
