Description

Fits 6.5 gallon glass acid carboys. Put a racking tube through the center spout, fit the cap over the mouth of the full carboy, then blow hard into the second spout to prime a siphon.

Acid Carboy Cap for use on older style 6.5 gallon acid carboys with the threaded tops.

This Cap is too small for our current 6.5 Gallon Carboy with a standard neck. See our Standard Carboy Cap for that carboy.
