    They look square, but i was expecting a taper to hold pressure in. Is my expectation out of line, or is the taper just REEEALLLLY subtle?

    Ones I have seen are square and go in either way. When the pressure gets behind the piston the seal will twist and 'seal'. When pressure released the 'twist' will return the piston.
