O-Rings Whenever removing O-rings, always clean them with a lint free cloth to remove old grease, sand and other deposits. Inspect them for any nicks, cracks or other damage. If any damage is evident, obtain a replacement. Greasing an O-ring is straightforward. Squeeze a small
amount of silicone grease onto your thumb. Work the grease between the
thumb, index and middle fingers. You can now pull the O-ring through the
fingers. When it's finished, the O-ring should have a gloss appearance.
If there are any lumps of grease or foreign bodies, clean the o-ring and
start again.
