We study the orientifold projections of the N=1 superconformal field theories describing D3-branes probing the Pseudo del Pezzo singularities PdP3b and PdP3c. The PdP3c parent theory admits two inequivalent orientifolds. Exploiting a maximization, we find that one of the two has an a-charge smaller than what one would expect from the orientifold projection, which suggests that the theory flows to the fixed point in the infrared. Surprisingly, the value of a coincides with the charge of the unoriented PdP3b and we interpret this as the sign of an infrared duality.
