Butyl rubber self-healing injection ports, often referred to as bottle stoppers, are essential in the world of mycology and mushroom cultivation. They are primarily used to minimise contamination when preparing liquid cultures or spawn masters.

Our high-quality rubber ports are constructed from thick butyl rubber, these ports maintain their shape even after undergoing multiple autoclave cycles. Unlike inferior alternatives, our butyl stoppers are entirely safe for high-temperature applications and can be reused multiple times.

These ports can be easily inserted in Mason jar lids, synthetic filter disks, or substrate containers. They are a key component in our BRF home mushroom cultivation kits. Ideal for:

Liquid cultures
BRF jars
Spawn masters
Substrate containers

Made from premium butyl rubber, each port measures 20mm in diameter and fits a 12mm hole. Used by professionals worldwide.

Installation in a mason jar lid is straightforward: drill a 12mm hole (or use a hole punch), file away any metal burrs if required, insert the port, and optionally secure it with heat-resistant silicone. This simple yet effective method ensures a snug fit. Each port can be reused multiple times, withstanding 5-15 punctures depending on needle size. A thinner 21g needle typically allows for 10-15 punctures.

For optimal use, remember to purchase sterile alcohol swabs to clean the port before each use, further reducing the risk of contamination.

Mr. O’Brien – 22 August 2019

I wouldn't use these with any needles thicker than 16g, I'd think 14g is borderline whether it self-heals, that's all I had, thicker than that it'll almost ruin the port. Posting to help others out there. get 16g-24g needles if you're using these. Otherwise, good quality ports at stupidly cheap prices!

prevents contamination. Seems of good quality – thick rubber. I'm using these to make liquid culture lids. Will buy again and recommend.
