Kimble® Kontes® HI-VAC® Right Angle Stopcock Valves with Extended Tip PTFE Plug
These right-angle, extended tip HI-VAC® stopcock valves have a polytetrafluoroethylene (PTFE) plug. Designed with a precision external thread for fine control. The accurately controlled valve seat and the extended tip on the polytetrafluoroethylene (PTFE) plug allow semi-needle valve control for both liquids and gases. The fluoroelastomer O-ring on the shaft backs up machined-in PTFE ring seals for high vacuum use. The O-ring is shielded from direct exposure to gases and liquids within the system by these PTFE ring seals. Plug is interchangeable with other KONTES valve bodies of the same size. Note: Polyacetal knob is not recommended for use over 110°C.
