Direct-Fit Replacement Liquid Post for AEB Kegs

Matching threads is the most critical step when replacing ball lock posts. This replacement liquid post features 19/32"-18 threading, making it a direct replacement for AEB kegs as well as select Cornelius models like the Spartan and Super Champion. If your keg's existing liquid post is cross-threaded, pitted, or refusing to seal properly around the poppet, swapping in a new post restores a gas-tight seal without having to retire the entire keg.

Distinguishing Liquid from Gas

Ball lock posts look similar at a glance, but their outer diameters differ slightly to prevent cross-connecting gas and product lines. This liquid-out post accepts standard black liquid quick disconnects. Unlike gas posts, which feature machined notches or a star-shaped base for easy identification, this liquid post has a solid, smooth base. Don't force a gas disconnect onto this post—it's sized specifically for your beverage line fittings.

Installation and Maintenance Tips

Before threading this post onto your keg, inspect the tank flange threads to ensure they're free of grit or dried syrup. Always install a fresh post O-ring and dip tube O-ring with food-grade keg lubricant to prevent micro-leaks under pressure. Thread the post on by hand first to prevent cross-threading the stainless steel, then snug it down firmly using a standard deep socket or keg wrench. Avoid overtightening, which can crush the dip tube flange or damage the internal poppet spring.
