Our standard sealant gun doesn't fit.** A: Right I have two sealant guns, a cheaper one that is small and one little bit more expensive and it fits this sealant tube. Another thing I done is cut the nozzle and push some sealant out the tube with a broom stick, then take a little hand saw and shorten the tube.
