  • Mininert valves can be used at temperatures up to 105°F
  • 0.036 in. (0.9 mm) opening accepts up to 20-gauge needles

Application

Mininert valves are leak-tight closures for vials and other containers. They are available in both crimp and screw thread versions. Only PTFE and glass are in contact with the contents of the container.
