Rubber Expansion Joints in NBR

Specifications

• Working pressure: 1.6 MPa (16 Kgf/cm²)
• Bursting pressure: 4.8 Mpa (48 Kg/cm²)
• Temperature: - 10° C / + 100° C

Note
• Thread with revolving flanges drilled UNI ASA 150 lbr, in zinced carbon steel.
• Rubber joints with vacuum ring are necessary when negative pressure is greater than 660 mm Hg.
• The pressure shown is valid for temperatures up to 80° C. For operating temperatures higher, the maximum working pressure holds the table below.
