1. An insulating jacket for covering a pipe fitting, the pipe fitting having an elbow extending between a pair of first and second couplings, the elbow and the pair of couplings having outer surfaces, the insulating jacket comprising:
a. an elbow housing comprising an insulating material dimensioned and configured to conform to the outer surface of the elbow so as to permit the elbow housing to envelop the elbow, the elbow housing having a length selected to extend between the pair of couplings and cover over the entire outer surface of the elbow between the pair of couplings;
b. the elbow housing divided along a length into first and second portions which are configured to mate together along elongated edges formed on each of the first and second portions, the first and second portions having first and second concave surfaces, the first and second portions dimensioned and configured such that when the first and second portions are mated together the first and second concave surfaces form a void dimensioned and configured to conform approximately to the outer surface of the elbow;
c. the insulating material is selected such that when the first and second concave surfaces are positioned over the elbow and the first and second portions are urged together, the insulating material at the first and second concave surfaces will deform against the outer surface of the elbow to permit the first and second portions to be mated to each other along the elongated edges;
d. a first coupling housing comprising the insulating material, the first coupling housing dimensioned and configured to conform to the outer surface of the first coupling of the pair of couplings so as to completely envelop the first coupling, the first coupling housing divided into first and second portions which are configured to mate together along an edge formed on each of the first and second portions of the first coupling housing, said first and second portions having first and second concave surfaces, the first and second portions of the first coupling housing dimensioned and configured such that when the first and second portions of the first coupling housing are mated together the first and second concave surfaces form a void dimensioned and configured to conform approximately to the outer surface of the first coupling; and
wherein the elbow housing has opposite first and second ends, with a first tongue and groove connector element configured to conform to the outer surface of the elbow formed on the first end of the elbow housing, and the first coupling housing has first and second ends, with a second tongue and groove connector element configured to conform to the outer surface of the first coupling formed on the first end of the first coupling housing, wherein the first tongue and groove connector element is configured to connect to the second tongue and groove connector element when the elbow housing and the first coupling housing are mated together.
