A cartridge for holding a supply of a flowable substance includes a cylindrical tube which is closed at one end by a slidable seal. An opposite end of the tube is closed by an integral end wall which is provided with a sealed nipple extending from the center thereof. The nipple is provided with an external thread. A line of weakness is formed about the tube near end wall. A flange extends radially from the outer circumferential surface of tube adjacent the line of weakness. A translucent strip is formed along the length of the tube to allow viewing of the position of the slidable seal within the tube. To use the cartridge in a grease gun, the seal is pulled out and the end wall cut off along the line of weakness. To use the cartridge in a caulking gun, the cartridge is simply dropped into the body of the caulking gun and the end of nipple cut off. To use the cartridge in a vacuum gun, the end of nipple is cut off and the nipple is screwed into the vacuum gun.
