Hydrophobic IP 68 Air Permeable Container Bottle Cap Air Foam Vent Gasket

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Ventilation & Liquid Resistance: Designed with a hydrophobic IP68 rating, the cap allows air permeability to prevent pressure buildup while ensuring waterproof performance for liquid containment.
  • Dual-Surface Engineering: Features a perforated side for precise airflow regulation and a smooth, sealed surface to maintain structural integrity and chemical resistance.

Key features

  • 1. Hydrophobic Aluminum Alloy Material

    • With a hydrophobic aluminum alloy body, you can ensure resistance to corrosion, chemicals, and moisture, even in harsh industrial environments. Unlike traditional plastic caps that degrade over time, this material maintains structural integrity for long-term use*.

  • 2. Integrated Pull Ring & Air-Permeable Vent Design

    • With the ergonomic pull ring and precision-engineered perforated vent, you can achieve easy access and controlled airflow during filling or pouring. This design prevents pressure buildup while maintaining a secure seal, outperforming non-venting caps prone to leakage or blockages*.

  • 3. IP68 Water & Dust Resistance

    • With an IP68 rating, you can guarantee protection against water immersion and dust ingress, ensuring safe storage of chemicals or liquids in demanding conditions. This surpasses standard caps with lower IP ratings, which may fail in wet or dusty environments*.

  • 4. Industrial Chemical Compatibility

    • Designed for industrial chemical storage, you can safely handle aggressive substances like solvents or acids without compromising performance. The vented design allows pressure equilibrium, reducing risks of container rupture compared to non-ventilated alternatives*.

  • 5. Certified for Rigorous Standards

    • Certified to IP68 standards, you can meet compliance requirements for industrial applications. This ensures reliability and safety in sectors where chemical containment and environmental resistance are critical*.

Product details

Hydrophobic IP 68 Air Permeable Container Bottle Cap Air Foam Vent Gasket

The Hydrophobic IP 68 Air Permeable Container Bottle Cap is an industrial-grade closure solution designed for chemical-resistant applications in bottles, packaging, and industrial systems. Crafted from durable aluminum with a hydrophobic coating, it combines precision-engineered perforations and a pull-ring mechanism to ensure reliable air permeability while maintaining structural integrity under harsh conditions.

Supplier's note

  1. Technical Breakthroughs:

    • Hydrophobic Coating: Reduces water absorption by 98%, preventing corrosion in humid or chemical environments.
    • IP68 Compliance: Outperforms industry benchmarks by maintaining seals at 1m depth for 30+ minutes.
    • Customizable Perforations: Precision-engineered holes enable tailored airflow control for applications like lab equipment or industrial reactors.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard chemical storage (e.g., consumer-grade containers) where cost-efficiency is prioritized.
    • Advanced Model: Suitable for medium-pressure systems (e.g., lab flasks) requiring enhanced airflow and heat resistance.
    • Pro Model: Designed for extreme environments (e.g., high-temperature reactors or cryogenic storage), with triple the chemical resistance of industry standards. Pair its ultra-fine perforations with the Pro’s heat tolerance to safely handle volatile substances like acids or solvents.

*Performance gains vs. Base Model. **Triple the ISO 1000:2022 benchmark for corrosive chemical exposure.
