What is a Bonnet Grease Fitting?

The vented cap bonnet grease fitting is a ½” National Pipe Tapered (NPT) fitting that is installed into the bonnet of the valve. The bonnet grease fitting provides a port for pumping grease into the cavity of the valve and onto the internal components of the valve. This is to reduce wear and provide longevity to the components of the valve.
