LB for Rigid Only?

Well then, I'm not sure what the LB listing says about liquid tight conduit but I do have another question. The reference material at Southwire shows the conduit to be listed for use from -55°C to 80°C. The marking on the conduit says 55°C to 80°C dry and 60°C wet.

While the ambient temperature of most applications that I encounter will never reach beyond 60°C/140°F I wonder about the conductors within the conduit.

I allow conductors to be rated using the 75°C column of Table 310.15(B)(2)(b) if the terminations are rated for 75°C but I am curious about a conduit that is limited to 60°C when used outdoors.
