Knowledge about MFC sealing parts and materials

Chloroprene rubber

1 Regarding the sealing material, chloroprene rubber, for the controller, is it only for ammonia, or can it be used for other gases?

Answer: Chloroprene rubber can resist ammonia corrosion and is also suitable for regular non-corrosive gases, but not for acidic corrosive gases. CS For the series products, only metal sealed products can be used with ammonia gas.

Metal Seal

2. For products with metal seals, which parts use metal seals?

Answer: All parts in contact with gas are metal, including all forms of sealing that isolate from the outside world.

Sealing Ring

3. Precautions when selecting sealing rings?

Answer: Ordinary fluororubber can be used for regular non-corrosive gases. When using ammonia, organic solvent vapor (such as acetone), or other strongly corrosive gases (such as HCL etc.), please specify this when ordering, and our staff will select the appropriate sealing material based on your specific gas usage.

Filter Element

4. Can the filter element of the filter be replaced, and what about the dryer?

Answer: The filter element of the filter can be replaced, and the dryer's element can also be replaced depending on the type.

Connector Size

5. MFC Common sizes and thread sizes?

Answer: Ф 6=M12*1.25 Ф 8=M14*1.5 Ф 10=M16*1.5

6，8，10 Refers to the outer diameter of the tube M12 Refers to the outer diameter of the interface thread 12mm

1/4 inch = Ф 6.35 3/8 inch = Ф 9.3 1/2 inch = Ф 12.7

1/4 Ferrule ==7/16 per inch 20 thread 1/2 Ferrule ==3/4 inch per inch 20 thread 1/4VCR==9/16 per inch 18 thread

1/2 inch pipe =DN20=3/4 inch (1/2 inch pipe is calculated with 8 as the denominator)

3/4 inch pipe =DN25=1 inch

DN15=1/2 inch
