According to some copy today, a certain component provides a "10% increase in wear and durability".
I can only assume that is an increase in wear resistance not in wear rate. 'Yes, our component is very durable, but wears out quickly...'
Besides, the OED definition of durable being 'hard-wearing', it's a tautology to say something offers an increase in wear [resistance] and durability: just say the thing is "10% more durable" and have done with it!
