This right-angle high-vacuum valve is designed with a precision external thread for use when fine control is needed.

• The accurately controlled valve seat and the extended tip on the PTFE plug allow control similar to a needle valve for both liquids and gases
• The FKM O-ring on the shaft backs up machined-in PTFE ring seals for high vacuum use which shield the O-ring from direct exposure to gases and liquids within the system
• Plug is interchangeable with other KONTES® valve bodies of the same size

Manufactured from 33 expansion, low extractable borosilicate glass.
