Apollo 3810201 Vacuum Breaker 3/8 in FNPT Bronze

The Apollo 3810201 is a bronze vacuum breaker with a 3/8 inch FNPT connection rated for 125 psi. It protects potable water systems by preventing back-siphonage when supply pressure drops. The silicone seal operates up to 212 degrees Fahrenheit. It meets Build America Buy America and Buy American Act requirements.

Installation and system fit

The unit threads directly onto a 3/8 inch female NPT port without additional adapters. Its compact height of 2 3/8 inches and width of 1 13/16 inches allow placement in tight mechanical rooms or fixture cavities. The bronze body resists corrosion from chlorinated water. No external power or control wiring is required for operation.

Sustained pressure and thermal performance

Under continuous 125 psi supply pressure the bronze housing maintains structural integrity without creep. The silicone seal retains elasticity through repeated thermal cycles up to 212 degrees Fahrenheit. The poppet returns reliably after each vacuum event, preventing leakage during prolonged low-pressure periods. The device contains no moving parts that fatigue under constant flow conditions.
