Co2 Leak Stopper (Star Seal)
This part screws into the end of some CO2 tanks to permanently replace the regulator washer. If your tank outlet doesn't have both male and female threads where your regulator connects, this will NOT work for you.
• Keeps your air tank working properly
• Replaces the built-in seal on the regulator stem
• Installs easily with a 5/32" Allen wrench
• Permanently stays in place - will not fall out
