Dynalon Products 40/50 PTFE Sleeves have an excellent finish of high quality Teflon, which makes them reusable. These functional lab tools do not require lubrication. They prevent seizing and galling of ground-glass joints, and can be used in a temperature range of -75 to 260 C. Elongated cone PTFE sleeves provide efficient thermal resistance. Measuring approximately 0.05 mm thick, and tapering approximately 1.10 inches on diameter, these sleeves are budget friendly and disposable, and available in cases of six units each.
