Metraflex - Metragator Metal Expansion Joint - Brochure

The Metragator is an externally pressurized expansion joint that has several advantages over other bellows joints.  Since the pressure is on the outside of the bellows, more corrugations can be added to the design resulting in a joint capable of more movement. The design also features pipe that acts as a liner and a casing that acts as a cover to protect the bellows from damage. The joint also features an internal guide making this a stable, rugged joint.
