O-ring chains have sealed, life-lubed link studs and bushes. However, these chains need lubricating at regular intervals to protect metal parts of the chain and the o-rings.
Lubrication also serves to keep the o-rings soft and pliable to ensure the maximum sealing efficiency.
Using a brush, apply a thin protective layer of high-density gearbox oil along the entire length of the chain both inside and outside (sec. 3 - 2, Fuel, lubricants and other fluids).
