Grease gun accessories: couplers and flex hoses for connecting a grease gun to grease nipples. The couplers are bright metal with knurled grip sections, in straight and angled styles, including one with a swivel head. The flex hoses are black with metal end fittings at both ends, in several lengths. A coupler pushes onto the grease nipple to deliver grease, and a flex hose lets the gun reach fittings in tight or awkward spots.
