20mm Super Heavy Duty Injection Ports

Heavy-duty, self-healing injection ports designed for repeated syringe access to mushroom culture containers. They reseal after needle withdrawal, allowing growers to access cultures without removing the lid.

• Purpose: Provides a durable, self-sealing access point for syringe injections

• Applications: Suitable for compatible liquid culture lids, grain spawn jars, and custom mycology lid assemblies

• Use: Fit the port securely into a properly sized opening in a compatible jar lid. Once installed, it provides an access point for injecting through the port with a syringe needle without opening the container
