ABSTRACT:
An end connector system for connecting a plurality of filter units in series has first and second end connectors secured to the ends of filter units. Each end connector has a base with a sealing surface and a connecting portion for engagement with the connecting portion of another end connector. The connecting portions have overlapping surfaces that overlap in the radial direction of the bases when the connecting portions are engaged with one another. A seal member is disposed between the first and second end connectors and is pressed into sealing contact with the sealing surfaces of the bases by a compression-generating member such as a tie rod. When the sealing surfaces are in sealing contact with the seal member, the overlapping surfaces of the connecting portions are separated from one another. As a result, all forces for producing a liquid-tight seal between the end connectors are generated by the compression-generating member and not by the end connectors themselves.
