Title: Flexible pipe connection with flange ring coupling - has axially compressed O-ring to produce clamping force against internal seat
Inventor: DIEHL MANFRED
IPC: F16L21/04
Filed: 1975-04-29
Abstract: The flange connector assembly is used to produce a flexible connection between two pipes. A location ring (1) has a collar (7) which provides an internal location seat for an O-ring (2).
