What is a BFM® fitting?

The BFM® fitting is a revolutionary and distinctive snap-in, flexible connector and spigot that eliminates the problems associated with traditional hose clamp systems.

A BFM® fitting generally fits between two pieces of machinery, either where a stationary machine connects to a moving one, or where access to product flow is needed. It comprises two steel spigots (or flanges) that are welded to your pipes and a snap-fit flexible blue-band connector that seats on the inside of the shaped portion of the two spigots, holding it securely in place. 

BFM®s patented blue band connectors provide superior performance:

  • 100% sealed, no mess, no leaks
  • Seals tighter under pressure
  • No product build-up means better hygiene
  • No tools required for fitting
  • Snap-in design makes installation easy
  • Standardised connector sizes mean you need to keep less stock
