Will it fit my calking tubes?
Yes! The serrated triple-tapered interior fits almost all caulking and adhesive tubes.
Does it work with silicone or siliconized caulk?
Yes! Just add a few drops of water in the Calkcap before inserting the nozzle. You’re good for months.
Is it reusable?
Absolutely, just keep it clean. It’s made from durable ABS plastic to be reusable.
What is your guarantee?
Calkcap is guaranteed to perform as stated:
Slide Calkcap onto the trimmed caulking tube push and turn slightly to secure. Calkcap limits the surrounding air to the cut material tip. Silicone and siliconized calk should have a few drops of water in the Calkcap to limit surrounding air. It doesn’t take much air to cure silicone.
