How long after you paste on a sticker do you have to wait before exposing the sticker to the pressure and heat of a pressure cooker?

I also glue mine down along with gluing around the rubber stopper so I wait 24 hours. But they are pretty sticky on their own. Also, don’t fill your pressure cooker but a couple of inches at the bottom so they are not under water. It works great!

What size drill bit should I use for the injection port?

I used 1/4 inch drill bit for 13.2 mm injection ports and for filters. You have to push and pull to get the injection ports seated, but once in place they are nice and snug and flat.

How do you attatch the stoppers to a bag? Im well versed on jars tryin to make some bags up

Cut off the underside part of the port and throw it away (the underside part of the port is for a jar application) clean bag and port with 70% & allow to evaporate until dry in a clean environment, attach to bag with heat resistant tape if application is before sterilization of grain.
