Hermetic seal

A Taper Joint Stopper with PTFE Sealing Ring. Optical transparency of the narrow sealing ring pressured by glass joint (right).
Grease is used to lubricate glass stopcocks and joints. Some laboratories fill them into syringes for easy application. Two typical examples: Left – Krytox, a fluoroether-based grease; Right – a silicone-based high vacuum grease by Dow Corning.
