Seeflex 040E can be used with 5 PSI on a a standard connector length (up to 200mm Long). Above this we recommend using a SS Ring support ring or the Seeflex 040E with a Camlon outer layer. Please contact a BFM represetative for more information.

We have standard length (up to 200mm Long) Seelfex 040E/Camlon connectors running at 12 – 15psi continually with no problems. We would not suggest that you run them past a peak pressure of 30 psi. You should contact a BFM representative to discuss these applications.

This varies greatly – refer to the ‘BFM® Limitations: Pressure’ and ‘BFM® Limitations: Negative Pressure’ information sheets.

The BFM® fitting at longer lengths is more susceptible to pressure and vacuum. The larger diameter connectors also become less rigid in the spigot and there is a possibility that the large diameters with long lengths will cause problems by pulling out of the spigot.

Yes – our FM1 breather bag is used when you have a vessel that you are trying to fill and need to vent air. The LM4 or LM3 connector can also be used if you require your BFM® fitting (connector) to breath, often due to pressures. The LM3 breathes more air than the LM4, but could also bleed more product. This will depend on pressure, product, application and conditions.

FM1 breather bags are available in lengths from 100mm (4") to 1 metre (3ft 3").

The upper limit we recommend for Seeflex 060ES is 1.3bar, although it has been tested well in excess of this. 

NB: This figure was from tests undertaken on a 250mm diameter connector 200mm long at ambient temperature.  Connector diameter, length and operating temperature will affect maximum operating pressures. Please refer to our 'Operating Pressure Guide' document.

We have replaced our pressure-resistant Camlon product with our new Seeflex 060ES product as we believe it has superior performance.  However, if you do specifically want Camlon, we can still provide connectors in a limited range.

The maximum continuous operating pressure we recommend for Teflex NP is 3PSI, and short surges to 5PSI.  Teflex NP is not recommended for use in negative pressure/vacuum operations.
