French standard quick release couplings, which conform to the French standard structure, come in three sizes: 6mm, 8mm/12mm. The French standard quick couplings mainly include the RPL series and the RMI series. The RPL series quick couplings are made of copper and electroplated, and are usually only open flow style structures. The connectors and plugs use red and blue rings to indicate the circuit, making circuit identification quick and easy. The connections and disconnections are easy and convenient, and the sealing rings can be easily replaced, making maintenance simple. The RMI series couplings are usually made of copper for the body and stainless steel for the shell, which is durable and reliable. The couplings come in both open flow-style and with vavle-style designs. This quick coupler has a nominal bore size of 6mm, 9mm, 12mm, 16mm, and 20mm, 25mm to meet different capacity requirements of customers.
