CIP - Clean In Place

BFM® fitting ideal in CIP (Clean in Place) installations.

The tight seal, impervious media and ease of removal of the BFM® connector help to make cleaning and maintenance during 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.

Many companies like to have a separate connector especially for the CIP process. BFM® can supply a product that is clearly marked ‘Wash Sleeve’  and the ease of change means this connector can be simply snapped in for the wash cycle only.


Good cleaning practices are important!

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.

Use the right concentration levels for cleaning chemicals

Below are the maximum concentration levels that should be used during a CIP for acid and caustic. 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.

  • ACID:              No more than 0.8%
  • CAUSTIC:       No more than 1.5%

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. We always recommend the BFM® connector is removed and wiped clean after the CIP process to ensure no residual chemicals.


Seeflex 040E Corner Connector is a cost-effective alternative to steel swivel-mounted tun dish drainage set-ups used in many Clean In Place (CIP) wash processes


The new Seeflex 040E Corner Connector is a flexible connector made from BFM®’s strong Seeflex 040E material, a clear, ether-based thermoplastic polyurethane alloy.  The unique shaped snap-fit connector 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

If you're designing new process line, extend the usability of the BFM® connector snap-fit concept to replace much of the expensive stainless steel involved in typical tun dish-type drainage arrangement with a Seeflex 040E Corner Connector.
