Conbraco 38-203-RK Repair Kit

The Conbraco 38-203-RK Repair Kit is the essential service set for maintaining 1/2" Apollo 38-200 series atmospheric vacuum breakers. Engineered for backflow prevention maintenance, this kit allows technicians to rebuild the internal assembly without replacing the entire brass valve body. It is fully compatible with Apollo valves 38203RK and Conbraco 38-203-01 models commonly found in irrigation and commercial plumbing systems. The kit includes the vacuum breaker float, O-ring seals, and retaining nut required to stop leaks at the vent or under the canopy. For contractors, utilizing factory-spec 38-203-RK parts ensures a tight seal against back-siphonage and restores high-performance flow rates. When troubleshooting a leaking 1/2 inch vacuum breaker, replacing the internal plunger assembly and seat disc using this kit provides a more reliable fix than generic alternatives, maintaining the device’s ASSE 1001 compliance and technical integrity in the field.

What are the signs that a 38-203-RK repair kit is needed?
If the vacuum breaker is constantly weeping from the atmospheric vent or fails to close during pressurized flow, the internal float and O-ring have likely degraded due to debris or age.

Is this kit compatible with 1" or 3/4" Apollo valves?
No, this specific kit is precision-engineered only for the 1/2" 38-200 series. Larger valves require size-specific internal components for a proper airtight seal.

Does this kit include the metal canopy for the valve?
This is an internal repair kit. It includes the functional sealing components like the O-ring and float but does not typically include the external chrome/brass canopy unless specified.
