The TM piston head is actually one of the best out of factory. The flanges of the piston head o-rings will flare when put under pressure and expand to seal the piston. It is supposed to be sloppy when not under load so that the piston can move in and out of the nozzle without getting caught in it.
How did you test for compression? Did you cover anything and blow into it to to check for leaking?
