Johns Manville - Zeston 2000 Mechanical Line Coupling Covers
The rapid acceptance of groove type fittings in lieu of welding has posed a problem to the insulation contractor, causing insulation contract prices to increase. These covers are designed to reduce these costs. Groove type fittings are usually insulated by multiple wrappings of insulation, finished off with molded or sculptured insulating cement and coated, lightweight muslin. This time-consuming, non-uniform and, at times, unsightly method of insulation can be eliminated with Zeston 2000 PVC mechanical line coupling fitting covers.
