Camelbak Omega Reservoir O-Ring
The symptom these O-rings will remedy is when you squeeze on a filled reservoir, you will see water drip out where the fill cap screws on. If you open the cap and inspect the O-Ring, you will be able to see cracks or other defects on your O-Ring (remove and stretch it out to really see the cracks). This happens eventually from general wear and tear, if this is your problem, buy this O-Ring, replace it, and enjoy your Camelbak again.
