Abstract: A method of protecting the end fittings of a tube or hose includes the steps of providing an end fitting that is attached to a hose or tube. Providing a heat shrinkable plastic capsule having a tubular portion with an open end and a closed end. Placing the plastic capsule over the end fitting until the closed end of the capsule is in contact with end of the fitting. Placing a magnet at the outer face of the capsule to maintain the end of the capsule in contact with the end of the fitting and heat shrinking the capsule onto the fitting. Removing the magnet from the end of the capsuled fitting.

Abstract: A system for cleaning the barrel of a gun which includes a compressible foam projectile, a source of compressed gas, and a flexible connector, such as a hose, for connecting the projectile with the cylinder is disclosed. The projectile resides within a nozzle which is secured to the hose. The cylinder is secured to one end of the hose. In order to clean the gun, the nozzle with the projectile inserted therein is placed within the barrel of the gun. The nozzle forms an airtight seal with the barrel. The compressed gas is released from the cylinder into the nozzle. The gas propels the projectile out of the nozzle and through the barrel. As the projectile travels through the barrel, it wipes the barrel clean.
