The Berkeley S08291 graphite packing ring is a service component for the packing assembly on specified Berkeley pumps. Its 1-3/4-inch inside diameter and 2-1/2-inch outside diameter match the graphite-ring selection for the B3ZRM catalog numbers below.
The specified B3ZRM assemblies use three S08291 rings at the graphite packing position and a separate S11092 metallic packing component. These are different parts even though their listed diameters match. The service requirement of three graphite rings is not a statement that this listing contains a three-ring package; confirm the quantity needed for your order.
