• Because Cup opening sizes vary slightly, and the pressure caps vary slightly, different amounts of tape may be required to tightly fit a given cup. Be prepared to adjust the number of layers of tape you use in order to fit your cup well. 
  • Colors can vary. 
  • Pressure caps are made from PETG plastic. 
  • I do not guarantee that the manufacturers don't change their opening sizes, nor that their cups are within tolerances.
  • At least one turner arm (pipe) purchased from us is required for correct pressure cap operation.
  • All pressure caps are made to order, and may require up to a 3 weeks for production.  We aim for less than 1 week.
  • Pictures of pressure caps are stock photos that may not be representative of the size you are purchasing.
