You can transfer hot wort to a no chill container with just a piece of silicon hose.
I clean my metre of silicon hose then,
fill it up with water and fold up each end to seal hose. Put one end over no chill container and other over kettle. Try to simultaneously release folding on kettle end (release folding so it goes into wort) and no chill end (important kettle end unfolding occurs sightly first - gloves might help if you don't like 90 degree wort contact with skin). The water within and gravity (oh yeah, the no chill container is lower than the kettle) creates a flow and will pull the wort into the container. Try to get the silicon hose to submerse into the liquid filling the container quickly to reduce oxidation. Have some towels about (and a second person might help but i do it myself) to relieve the burning sensation of holding the hose with hot wort in it in the kettle whilst draining (always fun) and to squeeze the air out of the no chill container when sealing it after.
Live on the edge.
Silicon handles hot wort, no issues with siphon and hot wort (though ss siphon would be cool). A tap would be best . . .
