Selection conditions of 90° outer joint:

1, fluid type, temperature (please select suitable fluid type, temperature body material and sealing material quick joint)

According to the fluid, the suitable body material, sealing material is different. For example, the quick connector is air. Steel is recommended, or brass or stainless steel for water.

2, liquid pressure (please select the quick joint suitable for the pressure performance of fluid pressure)

Fluid pressure is also the key to selecting a quick joint. Quick connection for oil pressure is 5.0Mpa(51kgf/cm2) 68.6 Mpa (700 KGF/cm&sup 2) Corresponding to the pressure characteristics, the structure of the fast joint is also different.

3, automatic on/off valve structure (please select the valve structure suitable for piping purposes of quick joint)

For the valve structure, there are two switch type, one-way switch type and two open. Due to the separation in addition to the two switch type, there is fluid flow from the pipe. So pay attention.

4. The use environment of the quick connector (please select the structure and material of the quick connector suitable for the use environment)

Combined with the use of environmental humidity conditions, dust conditions, as well as easy to corrosion and other use of the environment, to consider the selection of quick joint type, body material, sealing material.

5. Confirm that the selected quick connector connection threads should be consistent

In the use of products of different brands, Yin head and Yang head of the same brand should be used together. If cross-use is necessary, consult the technical personnel of the product supplier before use, and then use after confirmation.

6. Shape and size of installation

Determine the type and material of the quick joint and specify the assembly shape and size appropriate to the piping characteristics. Note that size is related to flow rate.
