Review: Buy this one - Excellent. Exactly as described. Fits a 15/32 inch hole perfectly. Use a step drill bit for a super easy clean hole in a jar lid. Oreilly sells a kit that includes a step drill bit with the correct size. Best value for money. Excellent durability, I tested one by puncturing it 20 times. As long as you use slightly different spots it lasts easily 10-15 punctures with a 16 gage needle.
Review: Worked flawlessly. - 100% success with zero contaminates. No problems being pressure cooked at 15psi for 90 minutes. The ports can be used multiple times, but they're so cheap I use new ones each time. 100 for $10 is an excellent buy.
