ABSTRACT OF THE DISCLOSURE A greasing attachment for a grease gun has been provided that enables one to access and thereby lubricate sealed bearings to prolong their life. The device comprises a normally plastic hose flexible enough to avoid or bypass obstructions in difficult access locations, one end of the hose carries a threaded fixture and a replaceable threaded grease nipple fitting, the other end of the hose carries a threaded hollow needle assembly connector with a tapered protrusion. Fitted in the connector is the needle assembly comprising a hollow needle, needle body, thread and an internal taper to cooperate with the connector protrusion. The cooperating tapers and coarse thread provide a high pressure seal with very easy replacement. The hollow needle is of a specific internal and external diameter and length for best results.
