Fluid power systems. O-rings - Anti-extrusion rings (back-up rings) Ingestion-build-98192 Attention is drawn to BS1 Scope This part of ISO 3601 specifies dimensions and tolerances for five types of anti extrusion rings, which are also known as back up rings: a) spiral type (T1); b) angle cut type (T2); c) solid type (T3); d) angle cut concave type (T4); e) solid concave type (T5). These anti extrusion rings are for use with selected O ring sizes as specified in ISO 3601 1 and the relevant housing dimensions specified in ISO 3601 2.
