1) I bought spare o-rings for the housing and the lens extension (5510.11). They
come in a little plastic bag and are not greased. I may not use them for many months or ever. Should I grease them for storage or leave as they are?
2) there are two o-rings on the 5510.11. One is maybe a few millimeters larger than the other although both fit in both the inner and outer grooves of the lens extension. Are they interchangeable or very specific to their placement. ( I assume they are not since they have different numbers but was wondering.........in case you had one spare left........)
thanks for for all your answers and for the great Ikelite service
