The base has an annular area corresponding to the bottom of the sleeve. A band is attached to the base for allowing the base to be affixed to the outer surface of the insulation. The sleeve has an elastic member extending outwardly of the opening at the top of the sleeve. The base is a generally flat sheet. The sleeve has an interior longitudinal axis extending transverse to a plane of the base. The sleeve and the base are formed of an elastomeric material. The sleeve and the base extend entirely around a cutout area of insulation formed at the valve handle of the valve.
