I didn't follow the instructions and just put the filter on the cap. Hole 1/4 (0.25) inch. You've been pressure cooker several times. at least 5. I installed them on solid stainless steel lids. Have washed the dishes several times, still holding up without problems. Although the price seems to be slowly increasing. I'm glad I got a few extras.
