D38 Drum ePTFE Vent Plug Overview
A professional pressure equalization solution for large liquid containers, chemical drums and industrial packaging systems.
The D38 Drum ePTFE Vent Plug is designed for large containers requiring reliable gas exchange while maintaining protection against liquid leakage and environmental contamination.
Using a waterproof breathable ePTFE membrane structure, the vent plug allows air and gas molecules to pass through while blocking liquid penetration.
During temperature fluctuations, altitude changes or transportation, the D38 helps balance internal and external pressure to reduce risks including drum swelling, deformation and vacuum collapse.
With an airflow performance of ≥300ml/min @12mbar and pressure resistance of ≥0.5 bar, the D38 is suitable for demanding applications such as liquid fertilizer, lubricant, peroxide and chemical packaging.
