The Elkhart Brass 57490000 O-ring is a replacement sealing component for 7000-EHD master-stream nozzles. Its AS-568-151 size measures 2.987 inches inside diameter with a 0.103-inch cross-section, helping you distinguish it from other O-rings used in the same equipment.
Choose this part when the nozzle service parts list calls for 57490000. It is an individual O-ring component, not a complete nozzle or a multi-piece seal kit; match the exact part number and installed nozzle model before ordering.
Servicing the specified O-ring lets you address that sealing component without ordering a complete nozzle. Check the surrounding sealing surfaces and the other seals during service so a damaged mating part is not overlooked.

| Exact replacement part number | Helps avoid substituting a similar-looking seal from another position in the nozzle. |
