Profile: Crist Group specializes in providing fabricate parts for the semiconductor industries. Side fusion welding eliminates excess fittings and provides full pressure capability while streamlining systems. Angular fitting welds allow for custom fitting configurations such as custom angle elbows and WYE pattern fittings. We use a proprietary process to form coils to specific dimensions that hold there shape under constant flex and internal pressures. Our coils have been tested up to 1,000,000 flex cycles without failure.
