Leakproof, Controlled, Metered Flow

Provides a consistent, small drop of your favorite lubricating oil, cleaner, bore solvent, stock stain or finish. Hollow steel "needle" accurately puts that drop of oil or solvent right where you need it most. Helps prevent over-lubrication, contamination and waste. Made from high density polyethylene plastic; fluorinated to resist breakdown from all common petroleum based solvents and protect any outer label from migration damage. Threaded aluminum top features a heavy-duty, inner, rubber seal and removable slip cap; both seal tightly and prevent leaks.
