PTFE Thin Wall Sleeves

PTFE sleeves are inserted between standard taper ground glass joints.  Our PTFE sleeves provide a vacuum tight seal between ground joints without grease. SciMac Thin Wall PTFE sleeves are precision ground to accurately fit all standard taper joints. PTFE sleeves eliminate the problem caused by seizure of joints as well as preclude contamination due to joint lubricants or leaking ground joint connections.   All SciMac sleeves are packed in tubular plastic containers to prevent creasing or damage during shipment and storage. Thin wall PTFE sleeves provide an economical choice for the Lab. Sizes range from 7/10 to 155/60.
