A filter for applications such as a lube filter for a large medium speed diesel engine application lube system is provided in which the open end cap carries three different seals including two radial seals that seal radially against a stem pipe in an axial abutment face and a seal gasket that seals against a mounting face of the housing. One of the radial seals is more reliable than the other while the other of the radial seals acts as a redundant backup and safety in the event that there is an improper installation or damage to the other seal as a result thereof.
