Product Specification

High Light IP67-IP68 Waterproof Breather Valve ，e-PTFE Membrane Air Vent Plug ，-50°C to +120°C Breathable Valve
Waterproof Breather Valve with Nut
High-Performance Waterproof Breather Valve with Nut - Precision Engineered for Reliable Pressure Equalization and Environmental Protection
Introduction
NewBase, a trusted manufacturer of advanced sealing and thermal management solutions, introduces its Waterproof Breathable Valve with Integrated Nut (Plastic Housing) — a compact, high-performance component designed to maintain optimal internal pressure while preventing moisture ingress in enclosed systems. Ideal for applications requiring long-term environmental protection, this valve combines durable plastic construction with advanced e-PTFE membrane technology to deliver reliable breathability, superior waterproofing, and exceptional durability.
Engineered for use in harsh environments, our waterproof breather valve ensures consistent performance across temperature extremes and varying pressure conditions, making it an essential component in electronics, automotive, medical devices, and industrial equipment.
Key Features & Advantages
  • Superior Waterproof Performance: Rated at IP67-IP68, the valve provides robust protection against dust, water immersion, and liquid intrusion, ensuring long-term reliability even in wet or submerged conditions.
  • Advanced e-PTFE Membrane Technology: The core features a microporous expanded polytetrafluoroethylene (e-PTFE) membrane that allows air and vapor to pass through while blocking liquids, dust, and contaminants.
  • Wide Temperature Range Operation: With a working temperature range of -50°C to +120°C, the valve performs reliably in extreme climates.
  • Integrated Plastic Body with Threaded Nut: Constructed from high-grade engineering plastics with excellent chemical resistance, UV stability, and impact resistance. Built-in threaded nut simplifies installation on M6-M40 ports.
  • High Air Permeability: Delivers 25-50 ml/mm²/min @ 1 psi, enabling rapid pressure equalization during temperature fluctuations.
  • Pressure Resistance & Safety: Features water intrusion pressure rating of 0.12 bar and meets UL94 V-0 flame retardant standards.
  • Customizable Design: Available in multiple port sizes (M6 to M40) and supports OEM/ODM customization.
  • Easy Installation & Maintenance: Screw-in design enables quick, tool-free installation without gaskets or seals.
