This black silicone O-ring is a replacement seal for a Cornelius-type ball lock post. It fits over the post to maintain an airtight connection between the keg and the ball lock disconnect, preventing gas or liquid leaks at the fitting. A simple, low-cost part worth having on hand for anyone running Cornelius kegs, since O-rings wear over time and are the most common source of a leaking post. Fit it in place of the old O-ring to restore a tight seal. A small spare that keeps a kegging setup running leak-free.
