Elalfex's range of Rubber Expansion Joints (compensators) are used as flexible connections within pipe systems to reduce noise, vibration and in some cases pipe movement or misalignment.
They are moulded single sphere type rubber bellows with swiveling metal flanges, of which the construction & lengths have since become the international recognised standard.

As the ERV's cover a wide range of industries globally, the range of certifications are quite vast and can be supplied on request:
