RUBBER EXPANSION JOINTS
FLEXIBLE PIPE CONNECTIONS,
PREMIUM CLASS
Our expansion joints are reliable and have been since 1956
RUBBER EXPANSION JOINTS
ERV expansion joints with swiveling flanges are used as flexible connectors in pipe systems. Our ERV's have been around since 1956. They relieve system strain by reducing vibration and noise, as well as compensate for static or dynamic movements. They are internationally recognized due to their premium construction and quality.
