Mechanical problem (Brake relay valve)

Hello,

Anyone ever have this problem:
Rear brake relay valve was leaking. Purchased a new one from parts store then installed it. The brand new valve is leaking from the same exact spot of the old one. The pic shows the new valve with the ABS valves connected. I DID NOT replace the ABS valves. They were not leaking.

Any input would be greatly appreciated.

Thanks in advance!!!
