The BF Series (ball face) couplings were developed primarily for chemical industry applications. They are a 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 of 5mm or 9mm and 12mm and larger bore sizes of 25mm and 50mm. Made of stainless steel, the BF series connects/disconnect process is totally squirt free, allowing minimal spillage or air inclusion.
