other lubricants! Other lubricants may cause deterioration or attract dirt and lead to leaks or premature failure.
O-ring Inspection - O-rings wear out over time. Inspect all O-rings whenever a sealed assembly is apart.
"Healthy" O-rings are soft, flexible and have not been pinched or nicked. Should an O-ring appear brittle, or have
apparent cracks, nicks, or evidence of being pinched or permanently compressed, it should be replaced. Sealing
surfaces should also be inspected while an assembly is apart. The surfaces should be examined to determine
that they are free of dirt, nicks, scratches, or damage, which may result in seal failure once reassembled.
O-ring Storage - O-rings should be stored in clean plastic bags to protect them from dust when not in use. Avoid
prolonged storage in direct sunlight as this may result in deterioration of the O-ring material. Stored O-rings
should be sorted with regard to type and size with that information noted on the storage bag. Use of an incorrect
O-ring can result in an ineffective seal.
Main and Light Dome Care and Handling
The domes should be cleaned with mild soap and water. They are acrylic and small scratches can be buffed out.
Do not use cleaners that contain alcohol or other solvents. Solvents can make the dome brittle.
