HI-VAC® T-Type Valve with PTFE Plug and No Tip O-Ring T-valve configuration, without tip o-ring exposure, allows closure of the bottom arm while vacuum or gases continue to flow through the sidearms.

HI-VAC® Right-Angle Extended Tip Valves with PTFE Plug 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 conforming to USP Type I and ASTM E438, Type I, Class A requirements Part Number Stem OD (mm) Bore Range (mm) Case Qty 826410-0002 8 0-2 1 826410-0004 9 0-4 1
