GC nuts

The design of the nuts and fittings are unique in that the fitting is flat faced and the point of the ferrule is towards the nut. This makes the system more robust since the angled portion of the fitting cannot be damaged. For more information, please refer to Product Data Sheet - GC unions [PDF].
