For standard Seeflex 040E connectors from 700mm (27.5 inches) to 1,000mm (39.5 inches) in diameter, a maximum length of 500mm (20 inches) applies. For connectors from 1,050mm (41 inches) up to the maximum of 1,650mm (65 inches) in diameter, a maximum length of 200mm (8 inches) applies. Under certain circumstances (and depending on the application) there may be a possibility for a slightly longer length, however, this would need to be discussed with BFM®.  Refer to our Quick Ref. Limitations Summary here for more information.

Standard Seeflex 040AS connectors up to a maximum of 650mm diameter are confirmed as Atex compliant - there are maximum length restrictions depending on the zones and processes involved.  Please refer to the following document for more information: BFM® Declaration of Compliance - ATEX

Yes, Seeflex 040AS is FDA and USDA compliant, and has 3A certification.

Yes – both CIP and manual washing is possible. Refer to the washing guidelines for Seeflex and Woven connectors.

Between 3 and 9 pH is generally acceptable, and outside this it is largely dependent on concentration, application and duration of contact. It’s important to remember that the pH scale alone doesn’t specifically help determining resistance of the materials – the pH scale will provide an indication of the strength, but product type, concentrations and temperatures are far more important. Our woven Teflex is an excellent alternative for use with acids or alkalis. This is a pure PTFE media which can be used on most products and up to very high temperatures. It is best to double check with us if there are any concerns regarding media compatibility.

It depends on the type of oil. Some oils are very aggressive and would degrade the polyurethane and the tight seal of the spigot connections can also be adversely affected by oils.

It is not recommended. It is preferable to reduce the IG to < 2m and use the Seeflex 040AS (antistatic).

Yes. The Seeflex 040AS has anti-static properties to ensure static does not build up through product flow (friction). The anti-static strap is required for any occurrence of electricity through the system. This could be caused by any unexpected current/charge. No connector will allow a large/sudden electrical charge to pass so the strap is required to ensure a spark does not pass between pieces of equipment.

There are Seeflex 040E fittings running through a number of metal detectors around the world with no problem. Metal detectors have an arc in which there can be no metal, you just need to ensure the spigots are welded outside of this arc (ie. welded to the pipe both above and below the metal detector). The BFM® connector then runs right through the metal detector. In the very unlikely event Seelfex 040E were to have any problems with false results, then the Seelfex 040AS could be used without issue. The metal detector specs will often tell you what ohm resistance the material needs to be within, you could check these.

We have BFM® fitting running with coffee in a number of plants around the world. There is no difference in terms of connector life than any other general application, it will depend on the conditions. There have been no problems with oils from coffee affecting the media.

Seeflex 040E, Seeflex 040AS, LM4, LM3, Teflex and Teflex NP can all be supplied with rings - but the maximum diameter for SS rings is 500mm or 1,000mm for plastic rings (and provided they are not TR (Tool Release) versions).  Seeflex 020E may be supplied on request, but Seeflex 060ES, Kevlar covers and Blackout Covers, cannot be supplied with rings. We also cannot make tapered connectors with rings. Please refer to our 'Quick Ref Limitations Summary' for more information.

No – BFM® Global Ltd certifies that in the manufacturing of our products we do not intentionally use any of the below mentioned substances and it is not foreseen that they could be produced: Bisphenol-A (BPA) Bis (2-ethylhexy) phthalate (DEPH) Dibutyl Phthalate (DBP) Benzyl Butyl Phthalate (BBP). Refer to our Seeflex Safety Declaration for more information.

1,000mm (39.5") is the longest we can manufacture a Seeflex 040AS connector with rings. This is a manufacturing limitation due to the nature of the 040AS material.  Please refer to our Quick Ref. Limitations Summary here for more information.

Yes – you can have plastic rings with 040AS no problem (up to a maximum of 1,000mm / 39.5").

No, to the best of our knowledge, BFM®'s material suppliers do not use or intentionally incorporate any of the following agents into the Seeflex 040E, 040As or 020E that we use for production of our connectors:

  • Bisphenol-A (BPA)
  • Bis (2-ethylhexy) phthalate (DEPH)
  • Dibutyl Phthalate (DBP)
  • Benzyl Butyl Phthalate (BBP) or any other Phthalates
  • Cyanuric Acid
  • Latex
  • Melamine
  • Nonylphenols
  • Oleamide
  • Silicone

 

Please refer to the Seeflex Materials Safety Declaration.

Yes - all of our products have been approved and are certified as 100% synthetic and Kosher all year round, including for Passover.  See our approval certificate (Certificate of Kashrut) here.
