Leaking at Poly/Brass Fittings for Humidifier
Posted by Rick on January 21, 2003 at 22:04:16:
I installed a new line to my the humidifier on my furnace from a kit. The assembly involves a brass compression nut with a tubing insert. The directions say to slide the polyethelene tubing over the insert and into the fitting as far as it will go and then wrench tighten.

No matter how much I tighten, I get leaking out of both ends (i.e. off the water supply line and at the furnace connection).

Are there any tricks of the trade to snug up the connection?
