Tubing adapters with Torion connection

- Hard-wall transfer tubing (e.g. PP or PTFE) is inserted through the threaded polypropylene bushing and PTFE- coated sealing ring of the adapter.
- Turn the bushing to make an airtight compression seal with the tubing.
- Use the optional solid-glass plug to make an airtight Torion seal when the transfer tubing is not in use.
