A jet pipe assembly containing at least one joint provided with a seal assembly to isolate, substantially, the fluid flowing in the pipe from the fluid external to the pipe;
- the seal being characterised in that the dynamic member (6) of the seal assembly is provided with both radial and cylindrical sealing surfaces.
A seal assembly including a static element (31), a dynamic element (19) and a spring (13) acting between the elements for urging the dynamic element against a sealing surface (7), wherein the elements have respective portions which slidingly engage for movement substantially along the line of action of the spring to provide a sliding seal between them.
An assembly provided with a seal assembly to isolate, substantially, fluid flowing in the assembly from the fluid external to the assembly;
- wherein the dynamic member (19) of the seal includes a transverse flange, the transverse flange having a cut out portion (37) into which part (38) of the static member (32) of the seal projects, thereby limiting relative rotational movement of dynamic member and the static member.
