1/4-28 Taper Thread

These fittings are also known as hydraulic grease fittings. Brass fittings are more corrosion resistant than zinc-plated steel fittings. Brass Fittings with a check valve prevent grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.
