Problem with McMaster is they only sell full bags of a size, so the cost is quite high and you'll have many many many left over! Look in the phone book for a...
Go buy a valve that doesn't use a guide rod - seriously. That or you 'could' drill out and tap the manual actuation port to put onto a blow gun. The valves...
There is a way to get around the guide rod. The diaphram should have a hole in the middle of it. This is where the guide rod goes. First you have to remove...
