Apollo 38LF10101 Vacuum Breaker

This lead-free bronze vacuum breaker installs on a 1/4 in FNPT connection to prevent back-siphonage in residential and light-commercial plumbing systems. It meets ASSE 1001-2008 and NSF/ANSI 372 standards for potable-water safety.

Verify thread size and pressure rating

Confirm the existing piping uses 1/4 in FNPT threads and that system pressure does not exceed 125 psi. The silicone seal operates up to 212 Degrees F, so ensure the fluid temperature stays within that range.

Sustained pressure and temperature performance

Under continuous 125 psi pressure the lead-free bronze body and silicone seal maintain a reliable seal without degradation. The ASSE 1001-2008 compliance confirms consistent backflow prevention during prolonged high-temperature service.

Questions about this item

Does the Apollo 38LF10101 vacuum breaker include any extra fittings or must I buy pipe tape separately?

The unit ships as a single 1/4 in FNPT vacuum breaker; pipe tape or sealant for the threaded connection is not included and must be purchased separately.

Which pressure rating should I select if my system runs at 125 psi?

This model is rated for a maximum of 125 psi, matching your system pressure exactly.

What does the 125 psi rating mean when the valve is installed in a hot-water line?

It indicates the maximum working pressure the lead-free bronze body and silicone seal can withstand at temperatures up to 212 °F while meeting ASSE 1001-2008 and NSF/ANSI 372 standards.
