CJ04-N008 Metal Threaded Waterproof Air Permeable Valve

Compact Metal Vent Valve for Outdoor & Industrial Electronics

The CJ04-N008 Metal Threaded Waterproof Air Permeable Valve is designed for electronic devices that require reliable pressure equalization, waterproof protection, and durable venting performance in compact spaces. With M04X0.7 thread specification, IP67 water resistance, and a robust stainless steel & aluminum alloy structure, this vent valve is ideal for outdoor electronics, industrial control systems, sensors, communication devices, and sealed enclosures.

Its compact threaded design allows easy installation into small housings while helping prevent internal pressure buildup caused by temperature changes, altitude variation, and environmental conditions. For manufacturers seeking a dependable metal vent valve supplier, CJ04-N008 is a practical solution for demanding applications.

Product Description

The CJ04-N008 metal threaded vent valve is a compact waterproof breathable component developed for electronic housings exposed to moisture, dust, and temperature fluctuations. Built with stainless steel and aluminum alloy, and finished with nickel plating, this valve offers strong mechanical durability and corrosion resistance for long-term field use.

With an airflow performance of M002 ≥60 ml/min and IP67 protection above 10 KPa, the valve allows air to pass through while helping block water intrusion. This helps balance internal and external pressure, reducing the risk of enclosure deformation, seal failure, and condensation buildup.

Its 5.0 mm thread length, M04X0.7 thread, and 0.3 ±0.1 Nm torsion make it especially suitable for precision electronic products and compact industrial equipment where space-saving venting solutions are required.
