The PROLUBE Professional Narrow Needle Nose Adapter is designed for greasing and flushing hard to reach hydraulic type fittings in hard-to-reach places. 

Each unit comes with small and large locking sleeves to ensure compatibility as well as securing the connection right onto the existing grease gun coupler. These locking sleeves snap onto sealed bearings, u-joints, high-pressure insert fittings and recessed fittings easily.
