Still Using Hose-Clamp Connections?

These common flexible-connection problems can lead to product loss, downtime, maintenance issues and unnecessary cleaning.

Powder leaking through a hose-clamped flexible connection

Leaking Product

Powder escapes through clamp connections, resulting in product loss, additional cleanup and increased dust exposure.

Frequent Connector Failure

Hose-clamped sleeves can tear, crack or wear prematurely, creating repeated replacements and unplanned downtime.

Product buildup around hose clamps and flexible connector

Difficult Changeovers

Clamps, tools and difficult alignment turn a simple connector change into unnecessary downtime.

Product loss around an industrial transfer point

Hygiene & Product Buildup

Crevices and poor-fitting connections create additional cleaning and sanitation challenges.

Flexible connector blown open under pressure

Clamp Failures Under Pressure

Conventional clamps can loosen or fail during pressure events, creating process interruptions and potential safety concerns.

Multiple industrial flexible connector sizes and spare parts

Too Many Sizes & SKUs

Inconsistent diameters, lengths and fastening methods complicate spare-parts inventory.

BEFORE & AFTER

The BFM® Difference

Use the slider to see the difference!

WITH TRADITIONAL METHODS

Powder leaks through clamps
Difficult to fit, variations & inaccuracies
Overpressure causes high-risk clamp failure
Frequent downtime for replacements, clean-ups

THE BFM DIFFERENCE ENSURES

No dust leakage and better hygiene control
Easy snap-in system and helps to streamline inventory
Stronger pressure resistance and reduced explosion risk
More durable material, quick changeovers and less downtime.

Replace clamp-style sleeves with a BFM® sealed snap-fit system

BFM® Fittings are premium hygienic flexible connectors designed to eliminate product leakage, even under pressure, while improving plant hygiene, production efficiency, and workplace safety.

Traditional hose-clamped sleeves often create leakage, contamination risk, cleanup labor, downtime, and safety issues. BFM® connectors use a snap-fit spigot system that creates a dust-tight seal without hose clamps, reducing maintenance and making changeovers much faster.

We do not just sell connectors. We help you identify the right connector style, fit-up, spigot configuration, and material for your actual process.

One leaking clamp connection can lead to product loss, repeated cleanup, sanitation headaches, and unnecessary downtime across the line.

How the BFM® System Works

BFM® replaces traditional hose-clamped sleeves with a simple snap-fit connector and spigot system designed for fast, reliable installation.

How the BFM flexible connector and spigot system works

Snap-Fit Cuff

The connector locks into the spigot groove with no hose clamps or external hardware required.

Seals From the Inside

Internal pressure expands the band outward, helping the connection seal tighter under pressure.

Faster Changeovers

Most connectors can be replaced in seconds, reducing labor and production interruptions.

Cleaner Operation

Less leakage, less buildup, fewer crevices and easier cleaning than traditional clamp-style connections.

Downtime Significantly Reduced for 24-Hour Flour Miller

“They’re one of the best things we’ve found…since installing the first two fittings, we’ve been replacing all of the remaining clamp-and-sleeve connectors in the facility with BFM® fittings. I’ve been putting them everywhere there’s a transfer point because they make things so much easier for our operators.”

CLEANING & REFITTING PROCESS SIMPLIFIED

Change From Clamped Connectors Helps Retain Valuable Product

"BFM^® fittings were installed to replace all existing hose-clip type connections on both the ultrasonic vibrating sifter and electronic magnet filter.

Now the internal cleaning process can be completed in a much shorter time due to the fast and easy snap-fit removal and re-installation process of the BFM^® fitting."

BFM® FITTING CONTAINS SUPER-FINE POWDER

Increased Production Efficiency

“Shortly after buying the first two BFM^® fittings over 13 years ago, our Continuous Improvement LEAN Process outcomes demanded we purchase more due to the time savings during set-ups, the reliability of a good seal and the ease of assembly and cleaning for our operators. We have never had a BFM^® connector let go or lose product which would be a costly event in the pharma industry. We now have them fitted to all our gravity transfer systems and product mixing bins.”

“Plaster is very fine and gets everywhere. It is difficult to contain, particularly when your connecting sleeve has holes in it! BFM® has been brilliant. The connector seals inside the spigot so it can’t chafe on the sharp edges and there are no jubilee clips to tear the fabric. It lasts for longer and best of all it doesn’t leak any dust.”
