Abstract

A brake or clutch assembly including a drum (18) and a transfer tube (36) for supplying hydraulic fluid to the drum (18). The transfer tube (36) includes a ring-like seal (59) for sealingly engaging the interface between the transfer tube (36) and the drum (18). A resilient O-ring (62), situated in a groove (64) on the transfer tube (36) and interposed between the ring-like seal (59) and the transfer tube (36), enables the ring-like seal (59) to cant relative to the transfer tube (36) without losing sealing engagement between the ring-like seal (59) and the transfer tube (36) and between the ring-like seal (59) and the drum (18).
