Guillemin Couplings are intended for application in industrial installations transferring, loading and unloading liquid and dry loose substances. The couplings were first designed in France and are compliant with EN 144208 / NF E 29572. Simple and easy connection is the key to their popularity. Two identical halves with two lugs are closed just by putting them together with the seals facing each other and by turning the locking rings so that the lugs are securely engaged. To tighten the connection, turn the locking rings with a hook wrench for Guillemin couplings by 1/4 a turn.

A Guillemin Coupling, also known as a Guillemin fitting or Guillemin connector, is a specific type of pipe or hose fitting that is typically used for the transfer of gases or liquids in industrial and laboratory environments. These fittings are known for their simple and reliable connections.

Key features of Guillemin connectors include:
1, Design: It usually consists of a male connector (convex head) and a female connector (concave head), the male connector has an external thread while the female connector has a corresponding internal thread.
2, Connection: Connection is achieved by screwing the threads of the male connector into the threads of the female connector. This type of connection provides good sealing and resistance to leakage.
3, Material: Guillemin fittings can be made from a variety of materials, including stainless steel, brass, plastic, etc., to suit different application requirements and chemical compatibility.
4,Applications:They are commonly used in gas sampling, gas analyzing equipment, laboratory equipment, medical equipment, and occasions where quick connection and disconnection is required.
5, Specification: Guillemin fittings are available in a wide range of sizes and thread specifications to suit different pipe diameters and pressure ratings.

Benefits: Due to their simple design, Guillemin fittings are easy to install and remove at a relatively low cost.
Guillemin fittings are particularly useful in applications where frequent connections and disconnections are required, as they can be operated quickly and do not require special tools. However, they may not provide as high a pressure tolerance as some other types of fittings, such as compression or ferrule fittings. When selecting Guillemin fittings, consideration should be given to the required operating pressure, temperature range, chemical compatibility, and long-term stability of the connection.
