Good item
Worked great on holes drilled in mason jar lids. If hole is small enough, you can cut the patches in half. Rubber port was of high quality. Both survived pressure cooking well.

SHIPs and filter discs
These work great! The ports are good for several uses and easy to replace. The filter patches hold up well in the pressure cooker and water beads off the material. I like the quantities for the price, a few hundred of each will last a very long time ๐

Reasonable Price. Good, Uniform Quality
Used only a couple so far, looks good. Don't anticipate any negitive issues with remainder. Very reasonabley priced.

These will do the job.
Filter stickers are functional. I wish this came with a small card or paper explaining the correct size hole for the injection ports. I can measure them with calipers but a simple piece of paper would have got that extra star.

Requires 9/32nd drill bit!
Item fair priced and as described. Another comment says 5/16th bit, but thatโs wrong. A 9/32nd bit is perfect to drill both holes and get a snug fit for the injection port.
User
So far so good.
So far so good. Used them for the first batch of liquid culture and put the jars through canning sterilization. They did not come detached and appears the adhesion is great.
User
Works well!
Both port and filter are easy to work with. I used RTV with some of the ports and found no difference with not using any! Filter stayed dry with a foil cover on top.
