Double Sphere Nitrile Rubber Expansion Joint

Product Description

Double sphere nitrile rubber expansion joint

FEATURES

• Applicable for suction and delivery (discharge).
• Designed for greater compression, elongation, and angular movement than the single sphere expansion joint.
• Excellent for absorbing thermal expansion and eliminating sound and vibration.
• Gaskets and packing not required.
• Good electrical insulator.
• Absorbs water pulsation and minimizes water hammering.
