Kadant Johnson 24a75200 Vacuum Breaker 3/8 Inch Brass

Product Description

The KADANT JOHNSON 24a75200 is a brass vacuum breaker designed to relieve unwanted vacuum conditions in closed vessels and pipelines. Featuring a 3/8 inch IPM inlet and a 1/4 inch threaded outlet, this unit is rated for service up to 300 psig and 365 degrees F. Vacuum breakers of this type are used to prevent vessel collapse and stop back-flow events caused by negative pressure. Plumbers and pipefitters working on steam, condensate, or process piping systems rely on this type of device for system protection.

This vacuum breaker is suited for industrial and commercial piping applications where unwanted vacuum formation poses a risk to system integrity. The brass construction makes it appropriate for steam condensate return lines, closed-loop process systems, and other elevated-temperature, elevated-pressure service environments. The compact size and threaded connections allow straightforward integration into existing piping configurations.
