This fitting meets the standard of the American Society of Mechanical Engineers's standards for 175 PSI safety blow-off valves. Meeting ASME codes and standards means this safety valve will never let you down
This blow-off valve is threaded with 1'4in NPT; this means it will fit just about any American air tank. Standard American air tanks are ported to 1'4in, 3'8in or 1'2in NPT. In the case of the latter two, you will require a readily available reducer bushing and you're good as gold.
