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 5 mm or 9 mm and 12 mm and larger bore sizes of 25 mm and 50 mm. Made of stainless steel, the BF series connects/disconnect process is squirt free, allowing minimal spillage or air inclusion.
