Hydrogen Generator Flashback killer/preventer.
Unit is 3 inches in length and available with 1/4" barbed ends.


This unit will stop flashbacks caused by a engine backfire from traveling to your hydrogen generator and blowing it up.
This is especially true for the people who are using those glass jars. don't be fooled into thinking that a inline check valve will stop a flashback either.
This is a must have for any HHO project.
