DEFINITION

Classification: 277/504

Flexible connection between seal and another part:

(under subclass 503) Accommodates gyratory or oscillatory motion wherein the seal for use on one of the relatively

movable parts (e.g., shaft, rod, etc.) includes a compliant link (e.g., flexible sleeve, flexible boot, flexible diaphragm, etc.) that accommodates oscillatory or gyratory motion between and secures the seal and the other of the relatively movable parts (e.g., casing, housing, etc.).

(1) Note. The seal may be part of and include a stuffing box.
