BFM®'s internal snap-fit design makes CIP a breeze.

Title Line

The tight seal, impervious media and ease of removal of the BFM® connector help to make cleaning and maintenance during clean in place (CIP) a breeze.

Seeflex 040E has excellent abrasion and chemical resistance. The connector can be used during the CIP process and very easily removed for cleaning any residual chemicals.

Good cleaning practices are important

Title Line

In most cases, maintaining the BFM® blue band connector is purely a matter of good housekeeping. If the CIP chemicals (usually either caustic or acid) are not washed off thoroughly then they will leave yellow stains on the Seeflex 040E media.

This is not contamination but simply discolouration of the media through a lack of rinsing. Chemical solution that remains on the connector will evaporate leaving a corrosive layer of chemical on the connector fabric.

It is therefore highly recommended that you wipe both the inside of the spigot and the connector after CIP to remove any residual cleaning chemicals.

Advantages of BFM® fitting with CIP

Title Line

No crevices to collect product so no build-up or contamination risk. Superior seal means they're safe for use in CIP cleaning cycles.

Strong and durable material designed to handle low concentration levels of caustic and acid often found in CIP wash fluids.

BFM® have a wide range of products that conform to important global standards such as 3A, USDA, FDA, EC & ATEX.

Less clean-ups and replacements plus faster, easier changeovers mean more productivity. 

Use the right concentration levels for cleaning chemicals

Title Line

The maximum concentration levels that should be used during a CIP for acid is 0.8% and for caustic it's 1.5%.  Any greater level does not provide an increased benefit in terms of cleaning the system, it is purely wasting chemicals. Excess levels will also adversely affect other parts in the system, such as seals and gaskets.


  •  Peroxyacetic acid and Sodium Hypochlorite as it is extremely harsh on rubbers, gaskets and seals, including the urethane of BFM® Seeflex connectors. If required, do not use in high concentrations or with temperatures over 45°C/113°F as it is too harsh.

    • Washing in water over 100°C/212°F or exposing to direct steam.

We always recommend that the BFM® connector is removed and wiped clean after the CIP process to ensure no residual chemicals.  Whilst there is potential for CIP chemicals to get into the internal gap during CIP, the BFM® fitting is still far superior to any other type of connector in this situation. 

Avoid Process Contamination

Title Line
BFM® have designed a unique identifier for connectors to be used exclusively in your CIP wash process.

The BFM® Wash Sleeve connector is a Seeflex 040E with a Wash Sleeve stamp that makes it easy for your staff to identify which connector should be used for your CIP wash process.

Using a BFM® Wash Sleeve connector reduces the risk of any residual chemicals contaminating your end product. Changing out the Wash Sleeve after the clean-in-place cycle also serves as a good reminder for staff to wipe the residue off the inside of the spigot to help extend the operational life of your process connectors.

Explore Other Applications and Conditions Using BFM® fittings

Title Line

BFM® fitting outperform traditional hose clamp systems in virtually every processing application and condition. Here are some common process applications that are challenging for flexible connectors:

BFM® connector with milk powder feeding into a hopper

If you operate under pressure, we know keeping your product inside your process brings all sorts of challenges, usually around dust control and connector failure. 

See how BFM® handles operating pressure.

BFM® Seeflex 040E with Vacuum

Processors often operate equipment under negative pressure to avoid leaking product out of machinery, but you need to ensure your connectors seal properly too.

Find out why BFM® is ideal for vacuum.

BFM® connectors installed on a potato flour sifter

The constant movement on sifters puts stress on flexible connections between equipment, and often causes problems like poor sealing, leaks and failures.

BFM® connectors installed on a metal detector

Metal Detector applications can be a challenging environment for traditional clamped connector systems because steel cannot be in near proximity to the detector.

See why BFM® is used with metal detectors. 

BFM® connector and static dissipation

Static dissipative connectors like the BFM® fitting range will help reduce the chance of spark discharges occurring that can potentially ignite combustible dust explosions.

Corner Connector - Ideal CIP Drainage Alternative

Title Line

BFM® Seeflex 040E Corner Connector - transparent background

A simple, cost-effective alternative to steel swivel-mounted tundish drainage set-ups used in many Clean In Place (CIP) wash processes. 

This uniquely shaped snap-fit connector made from our popular Seeflex 040E material features a tapered infeed end, 110º angled ‘corner’ bend and straight drain output end. 

It is designed to redirect the CIP wash fluid out of the process equipment at the end of the CIP cycle, helping to ensure the rest of the plant stays dry and product is free from chemicals used in the cleaning process.

Reduces volume of expensive steel pipework

The product was designed in response to requests from systems integrators who were designing new process lines and wanted a more cost-effective way to drain Clean-In-Place (CIP) wash water.

Replace your CIP system with a BFM® Corner Connector 040E.
