Just a quick thread about those of us that use Permatex RTV Silicone to seal cable/probe joints. After the first use of the silicone the thread portion of the cap broke off the top so I put a piece of plastic over the opening and screwed on the threaded portion to hold it tightly in place and put it in a zip lock bag. I haven't used the tube of silicone for a couple of years and the top 1/4 of the tube solidified. I cut through the tube with a sharp knife, leaving a solid plug as a cap for the tube and put it back in the zip lock bag since the rest a the silicone was liquid. I sliced the plug I removed into two disks and made a couple of probe holders. I just pushed a tooth pick through the center of each disk to make a pin hole and pushed the probe through for a snug fit. It's 700*F Permatex Ultra Copper RTV Silicone that sits on the grates or for vertical smokers it can hang from one disk laying flat on the rack. I may make some half dollar diameter molds out of plastic, since the silicone will peel off non porous surfaces after is solidifies.
