Test Port Valve question

Are pressure-temperature test valves for HVAC balancing valves a standard size? Or do they vary from manufacturer to manufacturer? The reason I ask is I bought test gages from a manufacturer that sells "green" pumps and tried measuring flow across the triple-duty valve of a company that sells "red" pumps and they couldn't connect. Aren't P/T ports standardized through-out the industry?
