Abstract
A bellows is configured for use on a valve. These configurations may include a corrugated section that is hollow to receive a valve stem therethrough. At its ends, the corrugated section can terminate at adapters. In one implementation, additive manufacturing can construct the bellows as a unitary or monolithic unit, avoiding welds or fasteners that can complicate manufacture of the parts. This techniques can create interfaces between the corrugated section and the adapters that comprises the same material as the adjacent parts.
