I am not familiar with "plumeasy" fittings. I am not sure if they even sell them in the USA. What are they used with, sounds like it is a fixable plastic? If it is similar to a compression fitting the proper tightening would be very important and sometimes flexible plastic would use a brass support tube inside at the cut end by the connector. Did you have any extra pieces? Hopefully someone with familiarity with the "plumeasy" connectors will respond to this thread. Also, you can look at the instructions and or package and see if they have a Helpline you could call.
