3" Tri-Clamp Oxygen Free HopDrop

Oxygen-Free HopDrop – Tri-Clamp Hop Addition Module

Closed-System Dry Hopping for Pressure Fermentation

Designed to eliminate oxygen exposure during dry hopping, the HopDrop enables clean, secure hop additions to your fermenter under pressure. It connects directly to your Unitank or pressure-rated conical via a 3" tri-clamp butterfly valve, maintaining a sealed environment throughout the process.

A built-in keg post allows purging with CO₂ prior to hop release, ensuring full control over oxygen ingress. The entire system uses sanitary tri-clamp fittings for fast setup and easy cleaning.
