TUBING ADAPTERS WITH TORION CONNECTION
The unique Torion connection ensures an air-tight seal between tubing and reaction vessels
when transferring air-sensitive materials.
1. Hard-wall transfer tubing
(e.g. PP or PTFE) is inserted
through the threaded
polypropylene bushing
and PTFE-coated sealing
ring of the adapter.

plug to make an air-tight
Torion seal when the transfer
tubing is not in use.
