Support Rings | BFM® Fitting

    BFM Fittings Support Rings SS/PE
    For Food, Chemical, Pharmaceutical & Mineral Processing Plants
    Superior to traditional hose clamped canvas/cloth/rubber connectors 

     

    Most BFM® fitting connectors can be supplied with support rings which help to keep the connector walls open when they are being used under negative pressure, or are longer in length.  They can also be helpful to support the shape of the connector when it is used in high-pressure applications, or in compression applications like bag loaders by keeping the connector open when compressed.

    These support rings are available in either stainless steel or plastic, which are used in conjunction with metal detectors.  Connectors can be made with single or multiple rings, depending on the diameter and length.  The rings are attached to the outside of the connector so do not come in contact with the product itself.

    Key Features / Uses

    • Most BFM® fitting connectors are available with support rings to help keep the connector open, particularly when under vacuum or for longer lengths
    • Rings are also useful in positive-pressure situations to help support the walls of the connector
    • Rings are available in either stainless steel or plastic (see table adjacent for size limitations on both)
    • Rings are fully encased in the material on the outside of the connector and therefore don’t come into contact with product flowing through the connector
    • Plastic rings are about 22mm larger than the connector diameter (connector diameter + 20mm for ring + 2mm for 040E layer that encapsulates the ring)
    • Standard distance between rings is 100mm (4 inches)

    * Size range is in mm, so inch conversions are approximate only. Restrictions apply for larger diameters, material types or when TR versions used. Refer to ‘Connector Sizes’ for more information.

    **Maximum number of rings for Teflex NP is 8 for Ø150 - 500mm & 6 for Ø100 & 125mm.

    Note: Tapered connectors cannot be made with rings.
