Adhesive Self-Healing injection ports, ideal for grain spawn bags and jar lids.
Keep your grains/substrate sterile, with these self-healing injection ports.
Made of high-quality silicone rubber, these injection ports feature a high-strength 3M adhesive specifically designed to adhere to low surface energy plastics such as polypropylene and polyethylene – making them ideal for spawn bags. The adhesive also increases in strength as it’s heated!
Our injection ports are designed by us, and manufactured to our exact specification after extensive testing in use.

Beware of cheap imitations, which are often just renamed off-the-shelf rubber pads, with all-purpose adhesives which perform poorly.
These are the real deal! Designed and manufactured for the purpose.
The specialist 3M adhesive used actually increases in strength with heat and time. For best results, you can apply the injection ports before sterilisation!
