Rubber bend (FB)
Rubber bends are fitted at high-wear sections of a pipeline system to change the direction of abrasive slurry where rubber pipelines cannot give the required bend radius.
Product information
The bends have an enlarged inner wear chamber of natural or synthetic rubber for abrasion resistance and a long service life. Strength comes from embedded metal elements and a load-bearing fabric frame.

Flange connection types
- 1“01” — embedded flangeThe flange is built into the bend body.
- 2“02” — rotating flangeThe flange turns freely, making bolt-hole alignment easier.
- 3“03” — rotating and embeddedTwo flange types can be fitted on one bend for easier installation. Connection dimensions to the customer's wishes.
- 4Inner working chamber rubberTwo standard versions depending on the particle size of the conveyed material: “01” for slurries up to 2.0 mm, “02” up to 10 mm.
