How to choose the material of the threaded waterproof and breathable valve

The threaded waterproof and breathable valve is a sealable installation component composed of polyurethane micro waterproof and breathable film injection molding, 

ultrasonic welding, and materials such as plastic, metal, and silicone. There are mainly micro penetration valves such as threaded and buckle types. The main performance 

indicators of permeable valves include breathability and protection level! The material is selected according to the appearance of the product in 

the orresponding color!

1、 Method

1. Based on the appearance of the product, the selection and corresponding or matching colors can be combined. Generally, we choose aluminum or stainless steel, and 

plastic is not within our own selection range!

2. Select the corresponding specifications of the threaded waterproof and breathable valve based on the product's functionality and other requirements. M12 is commonly

 used in outdoor lighting, as well as in industries such as solar photovoltaic, automotive manufacturing, and communication.

3. The material selection for breathable valves generally includes brass, aluminum alloy, stainless steel, plastic, yellow plating, etc.

2、 Precautions

Breathable valve packing should be separated to avoid scratches, etc

2. When installing, the torque requirement is suitable and the screw hole size is selected appropriately

3、 The main characteristics of threaded waterproof and breathable valves:

Waterproof and dustproof construction with a technical level of IP67 (customizable IP68), quickly restores breathability after contact with patient fluids;

High breathability can reduce the application force of shell sealing through balanced pressure;

The protective material film can be embedded in the plastic mechanical shell, which has the characteristics of inertness, singularity, chemical resistance, and 

UV resistance;

Has the ability to prevent moisture and moisture permeability;

4、 The main benefits of threaded waterproof and breathable valves are:

Protect sensitive electronic and electrical products;

Reduce the design and manufacturing costs of mechanical casings;

Used in extreme environments, it can extend the service life of the equipment and provide fault free maintenance;

Greatly reduce the occurrence of malfunctions in electronic and inductive products caused by various types of corrosion;
