It's a good idea to add this vacuum damper (also known as a "snubber") to the vacuum controller if your vacuum pump pulls more than 4 CFM. This will minimize on/off sputtering by the vacuum controller at the end of a charge cycle and potentially increase the life of the vacuum pump and the vacuum controller.
Thread size is 1/8" NPT on both sides so it fits our vacuum controller very well.
