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.
