Apollo 38LF10401 Vacuum Breaker

The Apollo 38LF10401 is a 3/4 inch FNPT vacuum breaker built from lead-free bronze with a silicone seal. It is designed to prevent back-siphonage in potable water systems operating up to 125 psi and 212 degrees Fahrenheit. The unit meets ASSE 1001-2008 and NSF/ANSI 372 standards for safety and material compliance.

Suitable applications and limits

This device suits plumbing installations that require a compact, code-compliant atmospheric vacuum breaker for continuous pressure service. It is not intended for applications exceeding the rated pressure or temperature, nor for systems needing a reduced-pressure principle assembly or a spill-resistant design. Buyers needing larger connection sizes or different end connections should select an alternative model.

Capacity and headroom

The breaker handles standard residential and light commercial flow demands within its 125 psi pressure ceiling and 212 degree Fahrenheit temperature limit. The lead-free bronze body and silicone seal provide durability under normal potable water conditions. Performance drops if system pressure spikes beyond the maximum rating or if the device is subjected to continuous back-pressure beyond its design intent.
