AMS Series Single Sphere Rubber Expansion Joints – Flange x Flange
*– Non Concurrent Ratings.
FEATURES
- Applicable for suction and delivery (discharge).
- Provides sound and vibration isolation.
- Gaskets and packing are not required.
- Floating flanges allow for easy installation.
- Prevents piping system and equipment breakdown by absorbing elongation and contraction caused by temperature variances.
- Absorbs water pulsation and minimizes water hammering.
