Overlocking means to hit the switch again after the car is fully lifted, it increases the pressure and causes seals to blow.

Overlocking is indeed a common cause. Lots of hopping can be hard on em too. You also should make sure your pumpheads are torqued down properly as well. I would reccomend getting a set of SRS Protector valves, they will prevent you from breaking tons of shit, and prolong all of your seals life. See em in this thread:

pumphead makes less pressure, and it takes longer to lift ride, and wont work as fast ;)

I read once that 25-28 foot pounds was reccomended, and thats where I always set mine to afterwards. I had problems with shredding o-rings before I did that, and afterwards they held up much better. No idea if thats the ideal specs, but it seems to work well for me and doesnt seem to overstress the threads in my aluminum block.
