Product Tips:

Silicone needs humidity to cure properly. That’s why Valco advises mechanics to apply silicone and allow it to set for 10 to 15 minutes before assembly. During this time, silicone absorbs moisture out of the air. This permits polymer “cross-linking”— the process that allows silicone to become rubber-like. If parts are put together while silicone is wet/fresh, it is likely the silicone will never set properly.

With Silicone tubes, once you remove the original screw-on cap, throw the cap away and put your nozzle on the tube. Between uses, cap off the current nozzle with a second nozzle from Valco’s Six Pack Replacement Nozzles™. For day-to-day use, this will prevent the silicone from curing. However, if your nozzle does plug up, take it off and replace it with a new nozzle. Set the plugged-up nozzle aside for a week or two and allow the silicone in the nozzle to fully cure. Once the silicone is cured, simply pull the silicone plug out with a pair of needle-nose pliers and the nozzle becomes re-usable.
