B8300 Series ISO B Stainless Steel Quick Couplings

Stainless Steel ISO B Quick Coupling

B8300 Series

AKJia’s B8300 is a special ISO 7241 Series B Quick coupling product that uses Stainless steel material. The dimensional requirements complied with ISO 7241 Series B, and the working pressure performance would be worse than that made by carbon steel. But the Corrosion resistance is much better. Usually used in medical, biopharmaceutical, chemical handling, liquid cooling of electronics, industrial, printing, and food processing. The Carbon steel version B8000 Series would have better performance under working pressure.

  • The body material is Stainless steel 316, doesn’t need any plating, suitable for the medical, biopharmaceutical, and food industries.
  • Interchangeable with All ISO 7241 B series couplings, that easy to replace any other brand that complied with the standard.
  • Poppet Valve is available to prevent liquid leakage when uncoupled and auto-open when coupling connects.
  • The ball locking mechanism that is easy to operate.
  • The working pressure would be lower than Carbon Steel (B8000 Series). need to check the working pressure to choose Stainless steel.

ISO 7241 Series B Standard specifies the interface dimensions, the necessary dimensions must meet the request from the ISO 7241 Series B standard, so the stainless steel ISO B quick couplings will be interchangeable among different suppliers and brands. Stainless Steel ISO B Quick Coupling is usually recommended for use in an application that transfers liquids like water, and chemical liquid, which doesn’t need a high-pressure performance but corrosion resistance. the dimensions of the connection for interchanging the replacement would be important. Other dimensions are not necessary. Also, check the seal ring material if you use quick coupling for your application.
