Query: leaks

No matter how much teflon tape I've placed on this, it continues to leak from the back connected to the main faucet when I leave the water on to a mainline out to my garden and timer. The quick connects stay on for a moment then slip and begin to leak. I yanked them off and threw them away. I much prefer the dials to turn the water on and off, now if I could only get the rear of the thing to quit leaking.
