Vacuum Breaker for Plumbing Systems
The Apollo 3820301 vacuum breaker installs on 1/2 inch FNPT connections to prevent back-siphonage in residential and commercial plumbing. Brass construction with a silicone seal handles water temperatures up to 212 degrees Fahrenheit. It meets ASSE 1001-2008 requirements for atmospheric-type breakers.
Pressure and Temperature Limits
Rated for a maximum working pressure of 125 psi, the device suits typical municipal supply lines and pump-fed systems. The silicone seal remains effective across the full 212 degree Fahrenheit temperature range. Installers must verify that system pressure and temperature stay within these boundaries.
1/2 Inch FNPT Connection Size
The single specification that determines fit is the 1/2 inch female National Pipe Thread connection. Systems using larger or smaller pipe threads, compression fittings, or press-fit joints cannot accept this breaker without adapters. Buyers needing a different connection type must select another model.
