The superfine applicator delivers oil exactly where it is needed with pinpoint accuracy and ease. The Teflon particles allow the oil to reach into awkward parts. The clean tip system with non-drip valve inside the plastic end prevents leakage when not in use. Light pressure will give one drop, whilst constant pressure will allow oil to flow. The metal tip is protected by oil proof gasket in the cap. Ideal for fishing reels, bearings, mechanical systems, guns & bikes.
