What are the connection methods for PFA fittings?

Threads, bead insertion, flaring, ferrules, and welding are currently the most widely used methods, mainly flaring and bead insertion.

How to determine the required tube fitting model?

Connector: First confirm the connection objects at each end of the connector, whether it is connecting tubes or corresponding connectors, then confirm the connection method, and finally determine the diameter

tubes: measuring the inner and outer diameters of tubes

If it is not possible to measure or provide samples, you can also provide specific models of the previous brands used for our assistance in matching.

PFA product production environment and raw materials?

PFA high-purity smooth tubes and PFA high-purity injection molded parts are produced and packaged in a thousand level clean workshop.

The raw materials for PFA high-purity smooth tubes include DuPont 451HP, Daikin 231SH, and Daikin 230;

The raw materials for PFA high-purity injection molded parts include: Daikin 211SH and Daikin 210

Why are there nuts made of PFA and PVDF materials for PFA fittings?

Due to the fact that the nut itself does not come into contact with the medium, different materials of nuts can be selected according to on-site usage needs. PFA material has better temperature resistance; PVDF material is more suitable for use at a temperature of 120 degrees. However, under certain usage requirements, the higher hardness of PVDF material will also become an important reason for its selection.

What type of connection method is commonly used for stainless steel fittings used in high-purity special gases?

Automatic welding, metal surface sealing connection (VCR)

Why do some stainless steel fittings require silver plating treatment on the inside of their nuts?

Silver plating can effectively avoid the problem of thread bite.

Are there any quality standards for PFA tube fittings?

According to industry requirements, if there is a clear SEMI F57 industry standard in the semiconductor industry, it must meet the requirements for metals, ions, TOC, and surface roughness
