PTFE Handle Sleeves

PTFE sleeves eliminate the problem caused by seizure of joints as well as preclude contamination due to stopcock lubricants and leaking ground joints. We manufacture ribbed reusable PTFE sleeves, 0.5mm -0.020” thick, with a reinforcing gripping  ring that provide a vacuum tight seal to 1mbar and also provide an easy and safe removal from standard taper ground joints. They are made for creating gastight, liquid tight and vacuum tight ground joint connections. Sizes range from 7/10 to 155/60
