NOTE: A standard 10,000 PSI (69 kPa) 16 ounce (475 mL) grease gun delivers approximately 0.04 oz. (1.18
mL) of grease with each pump, and a 24 oz. (710 mL) gun delivers approximately 0.06 oz. (1.77 mL) of
grease. The number of pumps listed represents approximately 20% of the total grease cavity volume in
end shield.
