Ultra-Vapour Lock

Ultra-Vapour Lock

Volatile organic compounds (VOCs) typically evaporate into the atmosphere when waste chemicals are decanted into a drum or when the drum bung is left open. No longer. The Ultra-Vapour Lock closure is specifically designed to trap those vapours and eliminate or significantly reduce fugitive emissions.


Polyethylene fill tube allows filling below the liquid level, eliminating agitation and splashing which contribute significantly to the evaporation process. Easy to install, simple slide fill tube through 2″ bung and securely thread bushing into drum bung. T-handle is easily hand-threaded into the bushing to seal off potential.
