The Chicago Faucet CGFT892-202KJKNF Vacuum Breaker Repair Kit maintains the integrity of vacuum breaker assemblies and safeguards potable water systems. The kit includes precision replacement components that renew the vacuum breaker’s internal sealing and venting, allowing it to admit air when negative pressure occurs and prevent contaminated water from siphoning back into the supply line.

This repair solution ensures dependable long-term performance.
