Self-Healing Injection Ports 13mm for Mushroom Cultivation

Versatile Use: These autoclavable rubber ports fit into a 12mm diameter hole and can be used to create your own culture or spawn jar lids.
Durable: Each stopper withstands approximately 30 injections before replacement is needed.
Easy Installation: Connect them to plastic canning jar lids or other substrate-based containers by drilling a hole and using silicone or high-temperature glue.
Filter Disc Compatibility: Ideal for synthetic filter discs—drill or slice a hole in the filter disc, glue the port, and let it dry.
Heat and Pressure Resistant: Designed to withstand autoclaving and pressure cooking.
Contamination Prevention: Properly sealed ports prevent contaminants from entering your growing environment.
Not for Ovens: Avoid using them in dry heat (e.g., ovens), but they thrive in wet heat sources like pressure cookers or autoclaves.
Bonus Tip: Keep your syringe needles safe—these injection ports double as handy plugs!
