AAP NBR rubber bellow, 2"

This AAP NBR rubber bellow is drilled to Table E. It is supplied in 5 sizes from 2" (50mm) to 6" (150mm). 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 NBR, rated -25 to +100 °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). NBR is not suited to ozone, ketones, esters, aldehydes or chlorinated and nitro hydrocarbons, so choose an EPDM bellow for those duties. Availability on these NBR bellows varies.
