A versatile filter structure adaptable for use in differently ported configurations includes accommodation for variations of bypass and shutoff valving and for filter element replacement from either end or centrally of the structure. A head casting is secured to a tubular housing and either may be the mounting device for the filter. A funnel shaped diverter having an oblique edge is removably mounted in the head casting and provides separation between inlet and outlet portions of the filter structure by means of an eliptical O-ring seal at the edge which engages the interior of the head casting. The diverter provides a smooth transition for fluid flow to the interior of the filter, supports one end of the filter element in the tubular housing, optionally houses a shutoff valve operative automatically upon filter element removal, and further houses a bypass valve for safeguarding against filter element blockage. The remote end of the housing which also supports the filter element consists in the different configurations of a welded-closed or removable end assembly, with or without a port and shutoff valving. An indicator mounted on the head casting is in fluid communication with opposite sides of the O-ring seal to monitor inlet and outlet pressure differentials. Dual diaphragms actuate and isolate a sensing piston in the indicator and a dual spring arrangement biases the piston for normal operation and to provide an indication of lack of filter element in the housing.
