Pan 50x Help

Hey all,
I am working on a Pan world pump for my closed loop but the rubber threading don't seem to be matching up with my threaded PVC very well. I can't screw them in for more than a quarter of an inch. This is causing the pump to suck air when I turn it on. Should I just silcone the threads and be done with it or is there something I am missing?
Thanks!
