PTFE Rigid Sleeves

Rigid Sleeves and Joint Adapters are grease-free, high vacuum seals for standard taper ground glass joints, with substantial shoulder for ease of handling and repeated use. High vacuum performance (leakage rate is less than 1 x 10-4 torr, litre, sec.-1) is attained using transverse sealing rings. Wall thickness of rigid sleeves is 0.5 0.5mm.
