About Us

Your premier supplier of electro-mechanical and hydraulic flange-to-flange connections

BSF, Inc. began in 1975 and primarily designed and produced fabricated Steel Pump/Motor Adaptors. Today, our product line has expanded to unlimited proportions.

BSF is now able to mate almost any flange-to-flange application with numerous configurations, styles and options. We are committed to manufacturing quality, USA made products at fair prices and with fast turn around. We take pride in the relationships we build with our customers and coupling manufacturers.

Did you know... that BSF’s name was created from the first initials of each our founders last names: Bull, Swihart & Farrier? When talking to new customer’s we sometimes have to introduce the company initials as "B as in Brian, S as in Sam and F as in Frank"… but really Brian, Sam and Frank aren’t related to us at all!


Our design and production teams will design and produce what you need for your particular application and guarantee the fit.
