AAP EPDM rubber bellow, 3"

This AAP EPDM rubber bellow is made with AAP's combined BS4504 PN16 and Table E flange drilling. It is supplied in 9 sizes from 1-1/4" (32mm) to 8" (200mm).

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.

Where this product is used

Key specifications

Choosing the right option

Match the flange drilling to the flanges on your pipework: this bellow uses AAP's combined BS4504 PN16 and AS2129 Table E drilling, so check it against both flanges. EPDM is not suited to mineral oils, solvents or aromatic hydrocarbons, so choose an NBR bellow for those duties.
