Slow leak from pex connection


I put baseboard hot water heaters in my basement, I finished it a couple months ago. I noticed last night I have a slow drip out of one of the fittings at an elbow/sharkbite cinch clamp fitting. I think my issue was that I put the clamp too close to the elbow, there is pex material showing all around the clamp but i have maybe 1/8" there (it was a tight fit). Is there some way to stop this leak, with some caulking or putty or something, without having to de-pressurize and drain my whole system in the middle of January just to fix this one fitting? Is it possible to put another clamp behind that one? I tried this but couldn't get the clamp together enough to get it to bite.

Any suggestions would be appreciated!

You can try a regular hose clamp behind that one.
But this will just buy you some time.

Drain the system and fix it right within a few months.

Forget about any caulk or putty idea

Yeah I plan on draining the system in the spring and doing it right, I just don't want to do it in the winter. I'll try a regular hose clamp.

Re-crimp it. Use go/no-go gauge.
