Cracked Z mount

The z mount was very tight on the conduit even without any screws in the assembly. Has I just started to engage the nylon insert in the nut the mount cracked. Any thoughts on repair or will it need to be replaced?

Should be fine, you can put a drop of superglue on it but there is not much of a load on that part.

Thanks for the quick response. While I am waiting on the glue to dry I have a question on the coupler nut. I am assuming that if I do not use the spring in the system I leave the spring and the extra 5/16 nut off. Correct?
