Abstract
A filter assembly employs radial interference between the received portion of a filter cartridge housing and the receptacle of a base. Radial interference occurs between a tapered end cap of the filter cartridge and a substantially cylindrical inside surface of the base receptacle. The filter cartridge end cap is tapered such that the interference increases as the cartridge is urged into the receptacle by a retaining collar. The tight fit improves resistance to vibration and shock applied to the filter assembly. Metal to metal contact at the interference points also provides a reliable electrical contact between the base and the cartridge to prevent accumulation static charges in the cartridge.
