Yes it's possible to over-tighten it, though not likely if hand turning it! Being plastic, it can warp and come away from the mating surface in spots, or the 'o' ring can get crushed, both allowing leaks. Also, you could easily strip the threads in the housing again because they're plastic.
But, just as w/ a spin-on oil filter, you should 'lube' the 'o' ring and then hand-tighten it, this is the best - not going to get near 19 lb.ft. with just your hand.
