Bulkhead D.O.T. Compression Couplers

Bulkhead D.O.T. Compression couplers, also known as terminal bolts or anchor bolts, are similar to standard bulkhead frame couplers in that they are made to attach to a panel or frame so that air can pass through but they feature a built in compression tube connector to make connections sealed and quick. They feature a brass body and nut for high corrosion resistance and a steel internal tooth lockwasher to anchor it in place when tightened.
