Replacement O & X Rings
Any 5mm condenser MP including the Pinner uses the 4x1.5
The "4mm" and the "XXX-L" MP use the #6-8 X-Rings. These will also work on your stock Vapcap condenser
Tinymight MPs use the 7x2.5 on stock stems and most of the stems I make. If you have a TM stem that is 2.5mm thick, use the 6.5x2
Price is for single O Ring
