Self-Healing Injection Ports (20mm / 10 Pack)
10 x 20mm diameter butyl rubber injection ports.
We recommend drilling a 10mm hole in your lids which will provide a tight seal after squeezing the rubber injection ports into.
Please note: these aren't the same injection ports that are in our grow kit lids - these are bigger, sturdier and perfect for jar lids.
What customers say
13 reviews for Self-Healing Injection Ports (20mm / 10 Pack)
These reviews are verified CusRev reviews. You will likely see large gaps in the years, these were either due to being on an extended break from Cylocybe due to life events or that we had gaps where we kind of stopped paying the CusRev contract. We unfortunately lost all of our Trustpilot reviews. If you want to leave a review, feel free to. We never pester for them, but only a teeny tiny number of people write them and it would mean a lot to us and our potential customers if you did when you get sent a review invite in a few months. If you order more than one product here, please don’t review every one of them - we had a customer buy 40 syringes and leave top reviews for each - we appreciate them but we have to remove them because they look manufactured. And for the love of mushrooms, don’t buy 40 products and leave 40 bad reviews without getting in touch first :)

Stopped at customs
In the 9 years we have been running, we have only had a couple of issues with parcels being stopped at customs - if this is the fault of us (USA seized a parcel once because we put a Cadbury's chocolate bar into a parcel as a treat ) then of course we will sort it out and take the hit. But if it's not our fault, then we will not cover any replacement cost. Luckily, this situation has probably happened a few times in all of these years.
