Product Overview
The D15 Press-Fit ePTFE Vent Plug is a compact pressure management component designed for packaging systems requiring reliable ventilation and liquid protection.
Integrated with a high-performance ePTFE membrane, the vent plug allows air and vapor exchange while helping prevent water, chemicals and external contaminants from entering the container.
It is widely used in agrochemical packaging, chemical containers, lubricant bottles, industrial packaging and protective enclosures where stable pressure equalization is required.
How D15 ePTFE Vent Plug Works
Pressure Equalization Through ePTFE Membrane
The D15 Press-Fit Vent Plug uses advanced expanded PTFE (ePTFE) membrane technology to balance pressure differences between the container interior and external environment.
The microporous structure allows air and gas molecules to pass through while blocking water, liquid chemicals and contaminants.
- Air exchange and pressure balance
- Waterproof breathable protection
- Reduced container deformation risk
- Improved packaging reliability during transportation
Advanced ePTFE Membrane Technology
Microporous Structure
Millions of microscopic pores create a controlled airflow path while preventing liquid penetration.
Hydrophobic Performance
The naturally water-repellent ePTFE membrane helps protect packaging contents from moisture and water ingress.
Chemical Compatibility
Suitable for demanding chemical packaging environments including pesticides, lubricants and industrial liquids.
Stable Ventilation
Maintains consistent airflow performance during storage, shipping and temperature changes.
Key Performance Advantages
Waterproof Protection
Prevents external water and liquid contaminants from entering the container while maintaining ventilation.
Pressure Relief
Helps release internal pressure caused by temperature fluctuation, chemical reactions and transportation conditions.
Leakage Prevention
Reduces risks of container swelling, deformation and leakage caused by pressure imbalance.
Long-Term Reliability
Designed for continuous operation in harsh industrial and packaging environments.
