This thin wall joint sleeve will fit inside a QuickFit glassware joint to prevent sticking without the need for grease.
An ideal choice to prevent sticking glassware without introducing grease which could contaminate the system.
The sleeves are around 0.05mm thick and will withstand low to medium vacuum application.
As the sleeves are so thin, you do not need to adjust the QuickFit fittings at all (i.e. 19/26 sockets will still fit to 19/26 cone with the sleeve in between the two)
PTFE has excellent chemical and thermal resistance.
