Piping Thread Standards
Quik-Test Compartmented Case
At Martel Electronics Corporation, we make a lot of pressure calibrators (oddly enough).
Since we also sell a lot of them internationally, a major headache is what kind of connector will the end user need. Part of the solution are our new Quik-Test connectors (see the previous post), but, more often, the problem is understanding just what the style of connector some one is asking about really is.
Engineering Toolbox is a great web site for answering all kinds of niggling questions like that. And, they have a great page that lists just about any kind of piping connection standard you can imagine.
Enjoy.
