Since 1978, Uniontown, Ohio-based JBM Industries has designed and manufactured reproduction rubber and machined parts for hard-to-find mechanical applications. The small manufacturer is especially known for replacement carburetor diaphragms and rubber sockets for vintage motorcycles and ultralight and light-sport aircraft, using its TSR compound for heat- and fuel-resistant parts. JBM also designs and builds its own tooling and can run customer tooling in its press.
