20 mm Self Healing Injection Port

20 mm Self Healing Injection Port is a Self Healing Rubber Stopper, 2 legs of the stoppers can create a better solid seal. Used for 20mm glass vial and liquid culture jars, fit about 13mm or 1/2″  diameter opening.  Excellent Heat Stability,  can be sterilized by steam under high pressure. It is reusable and will not lose shape. Great for liquid culture, BRF Jars, grain spawn jars,  and other substrate jars.

Installation & Use Instructions: 

  • We use a 1/2″ Drill Bit on our MycoLIDS™ to drill these out.
  • Be careful to drill straight down so that you don’t bore your hole out so they stay nice and snug.
  • You may have to back your jar lids off 1/4 turn so that the pressure build up in jars during Pressure Cooking or Autoclaving doesn’t pop them back out.
