Product Identity

The Apollo 3820306 is a brass vacuum breaker with a polished chrome finish. It connects via 1/2 inch FNPT threads and is rated for 125 psi maximum pressure. The unit meets ASSE 1001-2008 standards and operates up to 212 degrees Fahrenheit. It prevents back-siphonage in residential and commercial plumbing systems.

Suitable Installations

This breaker suits plumbers and facility managers protecting potable water lines from vacuum-induced contamination. It fits standard half-inch female pipe threads in new or retrofit applications. Builders needing larger pipe diameters or different connection types should look at alternative models. The fixed 125 psi rating also limits use in high-pressure industrial loops.

Sustained Operation

Under continuous demand the brass body and silicone seal maintain a reliable seal at the rated temperature ceiling. The ASSE certification confirms performance during prolonged pressure cycles rather than brief test spikes. Chrome plating resists corrosion from constant water exposure. The compact height of 2 5/8 inches allows installation in tight mechanical rooms without clearance issues.

Questions about this item

What piping connection do I need for the 1/2 in FNPT inlet on this vacuum breaker?

The valve has a 1/2 inch FNPT thread, so you need a matching 1/2 inch male NPT pipe or adapter to connect it.

Will the brass-polished chrome body and silicone seal handle the same 125 psi and 212 °F limits as my existing supply lines?

Yes, the breaker is rated for 125 psi maximum pressure and a 212 °F temperature range, matching typical residential supply conditions.

How can I confirm the device meets ASSE 1001-2008 after installation?

Look for the ASSE 1001 marking on the valve body; its presence certifies compliance with the 2008 standard.
