## Customer Reviews

### ⭐⭐⭐⭐⭐ Work perfect
*by J***R on June 19, 2025*

Been useing them awhile now, very strong rubber. Have literaly been through 100s of Pressure Cooks at 15psi for 90minutes a go. Quality product.

### ⭐⭐⭐⭐⭐ work well, flexible rubber
*by E***  on November 5, 2024*

These injection ports work well and are made of a soft, flexible rubber. I use large needles for my mycology cultures, and the ports last between 30-40 injections with a 16ga needle. Once I went past 40 injections, the rubber had trouble self-healing. The way the bottom is designed, the thick walls help for a strong seal with the vial, but they reduce the area that is thin enough to easily stick a needle through to 5mm so the injections are more concentrated to the center of the stopper and not spread across the total surface area. The injection ports last longer with 25ga needles, and you can get 300-400 injections before the stopper starts to have trouble sealing.

### ⭐⭐⭐⭐⭐ Perfect size for mycology Mason jar lids
*by S***E on June 27, 2023*

If you're looking for injection ports to make your own mycology lids, these are the ones you want. A 12 mm hole drilled in the lid, and these will press fit right in, no adhesive or silicone necessary. They have worked perfectly for me for my liquid cultures - no contamination. I have also used them on my grain jars by just spritzing down both sides with 70% isopropyl alcohol before putting them on.
