Claim 0:
1. A connection assembly, comprising:
a manifold including an upper plate and a lower plate; and
a connector pipe extending through the lower plate and the upper plate, the connector pipe including a flange disposed between the upper plate and the lower plate, wherein
the manifold is configured to attach a removable cartridge such that the connector pipe is inserted into a port of the removable cartridge and an O-ring is compressed between the connector pipe and an inner wall of the port, and
the flange has a width configured to prevent tilting of the connector pipe at greater than a maximum tilt angle, the maximum tilt angle based on at least one of a compression ratio upper limit and a compression ratio lower limit of the O-ring,, wherein the flange is configured to satisfy the following relationship:, L

W being the width of the flange of the connector pipe,
C being a compression ratio of the O-ring,
CL being the compression ratio lower limit of the O-ring,
CU being the compression ratio upper limit of the O-ring,
TO being a thickness of the O-ring without compression,
L being a length between the flange and the O-ring, and
h being a height of a gap provided between the flange and at least one of the upper plate and the lower plate of the manifold.
