Features
Sealing Design: The cap is equipped with a rubber or EVA foam sealing gasket inside. When tightened, it creates compression and rebound force, forming an airtight seal.
Anti-Slip Texture: The outer edge of the cap is typically designed with vertical ribs or knurling, increasing friction and making it easier to tighten manually or with a special wrench.
Optional Venting Function: Some DN150 IBC caps are designed with a vent hole, allowing internal gas to escape and balancing internal and external pressure. This helps prevent deformation of the container when filling hot liquids or when temperature increases.
Main Types
Based on function and application scenarios, DN150 IBC caps are mainly classified as follows:
Blind Cap:
Features: Fully sealed with no openings.
Application: The most common type, used for general liquid storage and transportation, ensuring complete airtight sealing.
Vent Cap / Breather Cap:
Features: Equipped with a vent hole at the center or side, usually covered with a breathable membrane or filter.
Application: Suitable for liquids that require "breathing" (such as fermentation liquids) or to prevent excessive internal pressure changes.
Pressure Relief Cap:
Features: Integrated with a small pressure release valve.
Application: Used for transporting pressure-sensitive special chemicals to ensure safe pressure regulation during storage and transport.
Applications
- Chemical, Coatings, Ink & Solvent Storage and Transportation
- Food & Beverage, Pharmaceutical, and Daily Chemical Raw Material Handling
- Flammable and Explosive Media (with anti-static versions available)
- Materials Requiring Pressure Balance (with vented/breathing caps)
