Established in 1866, Mercer Rubber Company manufactures rubber expansion joints and flexible connectors for demanding piping and duct systems. The Hauppauge company is the oldest U.S. manufacturer of rubber expansion joints, with more than six decades focused on the field and about 70% of its work customized to specific design requirements. Its engineers and in-house fabrication team also support unusually large applications, including a 96-inch pressure-balance installation for a Malaysian power plant.
Adsco Manufacturing LLCSince 1877, Adsco Manufacturing has designed and made industrial expansion joints that accommodate thermal movement in demanding piping systems. Born from the first district heating system in Lockport, New York, Adsco’s engineers invented the expansion joint itself and still build custom slip-type and bellows solutions for industries ranging from power generation to chemical processing. The Buffalo manufacturer’s history remains closely tied to practical engineering: solving a problem in steam piping and refining that solution for modern industrial service.BUFFALO, NY
