Description
When your HVAC or plumbing installation uses a ½″ atmospheric vacuum breaker (AVB) from the 38-200 series and over time wear, debris or seal failure compromises its function, the Conbraco 38-203-RK Repair Kit offers a complete OEM-specific solution. This repair kit is designed to rebuild the AVB to its intended performance, restoring back-siphonage protection and ensuring the system continues to comply with required plumbing and HVAC safety standards.
Key Features
- OEM quality repair parts: Manufactured by Conbraco/Apollo to match the original equipment’s materials and tolerances, ensuring reliable fit and function.
- Designed for the ½″ size AVB in the 38-200 series: Specifically built to service the 38-203 model and similar, this kit helps technicians avoid sourcing multiple generic parts.
- Comprehensive kit contents: Includes key internal components (such as seats, discs, O-rings, caps) required to service the AVB and restore full operation.
- Cost-effective maintenance option: Instead of full replacement of the AVB body, using the repair kit keeps downtime low and replaces only the worn internal parts.
- Supports system compliance & safety: Proper functioning AVBs are important in HVAC and plumbing systems to prevent back-siphonage and contamination of potable or closed fluids.
