BF Series (Ball Face)

Low pressure, clean break coupling

 

 

 

 
Link to .pdf brochure for BF-025 & BF-050  

The BF Series (ball face) couplings were developed primarily for chemical industry applications. They are a high clean break coupling which can be used for both non-lubricating media, such as demineralized water, process liquids, "dry" gases and solvents or lubricating media, such as oils or soap solutions. Design features provide for easily cleanable surfaces. 

The BF Series couplings are available in small bore sizes (above left) of 5mm, 9mm and 12mm and larger bore sizes (above right) of 25mm and 50mm. Made of stainless steel (other materials available), the BF Series connect/disconnect process is totally squirt-free, allowing minimal spillage or air inclusion.
