Fuzhou Hongxing Machinery Co.,Ltd is a professional factory manufactures and distributes camlock couplings/ cam & groove couplings and other disconnectts fittings for low-pressure liquid and dry tranfer applications.Our cam & groove couplings are strong and durable .The design and construction of these couplings have superior quality boday with precision machined surfaces made in Fuzhou , China.

From its humble beginnings as a machining job shop in 1994 the Fuzhou Hongxing Machinery Co.,Ltd has grown to a global supplier for companies seeking a high quality product at a fair price. Our goal is to be the single source for all of your pattern development, casting, precision machining, fabrication, heat treat and plastic injection molding needs. Our success stems from an uncompromising commitment to three core values: quality, service and integrity.

The Quick Connect/Disconnect Couplings provide for quick connecting and disconnecting by means of the camming action. This camming action allows pipe and hose connections to be made without the need of hand tools or difficult threaded connections.
Cam and groove couplings are made up of two parts, male (adapter/plug) and female (coupler/socket) that work together. The male adapter is simply inserted into the female coupler until contact is made with the gasket. Both cam arms on the coupler are then pressed down/closed simultaneously to produce a uniform gasket compression between the seal surfaces. This seal is created because the cam arms of the female coupler fit snugly against the groove of the male adapter. A positive seal requires that the surfaces on the gasket seat, the adapter face, and the gasket are smooth and uncontaminated. Also cam arms must be in the full closed position for proper locking of the coupling. To disconnect both arms must be lifted/opened simultaneously to release the seal and release the connection.

All Quick Connect/Disconnect Couplings in every metal and size through 6”parts are manufactured to interchange with all products produced to Commercial Item Description AA-59326C. All “RFQ’s” identified as Government will be quoted with the required components and castings to meet the AA-59326C Commercial Item Description. Couplings not interchangeable in the industry are sizes 8” through 12”. No standards were established by the government for these sizes. Quality is controlled in every phase of manufacture as is required for compliance to MIL-C-27487 and A-A59326C. Our Coupling’s quality management system is certified and conforms to the requirements of ISO9001.
