Abstract: A universal insulation (10) is the subject of this patent application. The insulation (10) is bifurcated into two portions (16,18) for application to a fitting in a fluid flow or distribution system. Cut-outs (26) are provided in edges (20, 22) of the portions (16, 18) which, when apertures are formed therein, accommodate portions of a fluid fitting therein. Portions (16, 18) of the insulation (10) can have additional cut-outs (28) formed wholly within one of the portions (16, 18). These cut-outs (28) can accommodte portions of a fitting extending generally transverse to a plane defined by other portions of the fitting. Novel means can be employed for maintaining the portions (16, 18) in a mated configuration.
