Often used on earth movers, mining equipment, and other heavy machinery, these fittings have a T-shaped top that holds the dispensing tip in place so it won’t pop off when adding grease. They're best for machinery requiring high volumes of grease because they let more grease pass through than standard grease fittings, thanks to a larger opening. An integral check valve prevents grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.

For more control over the flow rate of your grease, choose these gas-driven dispensers over spring-driven dispensers. Their continuous flow automatically adjusts based on the dispensing duration you set on their dial (from one to 12 months). Because you control when they’ll empty, these dispensers make it easy to plan maintenance. To prevent over-lubrication when your machine is down, turn the dial to zero to cut off flow without uninstalling the dispenser. They’re best for applications with consistent temperatures, so the viscosity of the grease won’t change how quickly it flows. All have a clear bowl so it's easy to monitor the grease level.

Rated IP68, these dispensers seal out dust and water from temporary submersion. They’re ATEX certified for use where explosive gases and dust could be present, such as mines and oil refineries.
