AAP EPDM rubber bellow, 4"

This AAP EPDM rubber bellow is drilled to Table E. It is supplied in 16 sizes from 1-1/4" (32mm) to 24" (600mm). A rubber bellow is a flexible joint moulded in a spherical shape from heat-resisting synthetic elastomer, with metal floating flanges. Installed in a piping system, it absorbs movement in three directions: axial (elongation and compression along the centre line), lateral (offset from the centre line) and angular (bending about the centre line).

The body is EPDM, rated -30 to +120 °C, with a nylon cord fabric lining and a hard steel wire frame. Applications: air, compressed air, water, sea water, hot water and weak acid.

Key specifications

Choosing the right option

Match the flange drilling to the flanges on your pipework: this bellow is drilled to Table E (AS2129). EPDM is not suited to mineral oils, solvents or aromatic hydrocarbons, so choose an NBR bellow for those duties. Working pressure steps down with size: 1,600 kPa up to DN300, 1,000 kPa for DN350 and DN400 and 600 kPa for DN500 and DN600.
