Apollo 3820406 Vacuum Breaker Specifications

This Apollo 3820406 vacuum breaker provides backflow prevention for plumbing systems with a 3/4 inch FNPT connection. It is built from brass with a polished chrome finish and a silicone seal for durability. The unit is rated for a maximum pressure of 125 psi and a temperature range up to 212 degrees F. It complies with ASSE 1001-2008 standards for atmospheric type vacuum breakers.

Installation and Operating Parameters

The compact body measures 3 inches in height and 2 inches in width for integration into existing piping. Its FNPT threaded inlet allows direct attachment to standard 3/4 inch female pipe threads without additional adapters. The silicone seal maintains integrity across the full 212 degree F temperature range during normal operation. Brass construction resists corrosion in typical potable water environments.

Sustained Load Behaviour

Under continuous pressure up to 125 psi the brass body and silicone seal maintain a reliable seal without deformation. The ASSE 1001-2008 certification confirms performance during prolonged exposure to high temperature water at 212 degrees F. The polished chrome finish protects the underlying brass from long-term environmental oxidation. This device is not intended for applications exceeding the stated pressure or temperature limits.

Questions about this item

How is the Apollo 3820406 vacuum breaker installed and what step do people often get wrong?

Thread the 3/4 in FNPT connection onto the pipe using pipe sealant; the common mistake is over-tightening and cracking the brass-polished chrome body.

What maintenance or replacement will the Apollo 3820406 need later?

The silicone seal can degrade over time; inspect annually and replace the seal if water leaks or the breaker fails to vent.

What limit shows up first under sustained use on the Apollo 3820406?

The 125 psi maximum pressure rating is the first limit; sustained pressure above that can damage the valve before the 212°F temperature limit is reached.
