BFM® connectors can be fitted with stainless steel or plastic support rings to help keep the connector walls open.
Product Description
Most BFM® fitting connectors are available with support rings to help maintain the shape of the connector and keep the walls open for product flow, particularly when under vacuum or for longer lengths.
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.
Application
Useful in both negative and positive pressure situations, rings help support the walls of the connector in higher pressure environments.Exclusions
- Tapered connectors cannot be made with rings.
- See Specifications below for details on which connectors can have Rings.
