Self Healing Injection Ports come in gray or orange. The two stoppers fit (13 mm) dia opening. The gray are 3/4″ across the top, 5/16″ top to bottom. The orange are 9/16″ across the top, which has a dimple in the center to help guide a needle, and 9/16″ top to bottom.
Myco Supply offers two different sizes which of self healing injection ports which are most commonly used. These ports maintain a constant shape. Most will use these ports in conjunction with a plastic canning jar lid or some other spawn/substrate based container. Connecting the ports to the lids is as simple as drilling a hole and adhering it to the lid! We recommend using a silicone or high temperature based glue.
Many mushroom growers will also use self healing injection ports in synthetic filter discs. The same procedure applies to filter discs as with plastic canning jars. Simply drill or slice a hole the size of the self healing injection port in the synthetic filter discs, glue then let dry.
If using the injection ports just for spawn masters. Growers can use any standard silicone glue. If the container is being placed inside a pressure cook or steam sterilize. You should use a high temperature glue that will withstand both heat and pressure.
The self healing injection ports can withstand high temperatures and pressure but if the glue you use can not. Then you’ll have a poor seal which can lead to contamination.
Do not use self healing injection ports inside of an oven. Self healing injection ports can withstand a wet heat source such as a pressure cooker or autoclave. As a result, the ports will not survive a hot dry heat. Lastly, a quick tip… Loosing a syringe needle is never fun. The self healing injection ports work as a great plug!
