Russia Type Gost Coupling Female Thread

The Russia type GOST coupling with female thread is the other half of the hose connection system that mates with the male-threaded GOST coupling. Just like its male counterpart, it is designed to meet Russian GOST standards for fittings, which ensures compatibility and reliability in the applications where it is used. These couplings are often utilized in water supply, firefighting, and a variety of industrial applications.

Here are some details regarding the female-threaded GOST coupling:

1. Thread Compatibility: The female thread is designed to connect with a male GOST thread of the same size and thread pattern. The specific threading is determined according to GOST standards which may differ slightly from other international thread standards.

2. Coupling Mechanism: The female GOST coupling features a recessed slot to accept the locking head’s lugs from the male coupling. Once the male part is inserted into the female part, it is rotated to lock the lugs in the slots, securing the connection.

3. Materials: Like the male GOST coupling, female counterparts are typically made of materials such as aluminum, brass, or stainless steel. The choice of material often depends on the application’s demands such as required strength, corrosion resistance, and compatibility with the conveyed medium.

4. Sizes: They also come in various sizes to align with the diameters of the hoses or pipes they are intended to connect with.

5. Usage: These connectors are primarily seen in applications that call for quick and secure hose connections, including firefighting hoses, industrial fluid transfers, and sometimes in oil and gas industries.

6. Standard Compliance: Being made according to GOST standards, these couplings should seamlessly connect with other GOST-compliant equipment, ensuring they work as expected in systems designed around these standards.

When selecting a GOST coupling with a female thread, one must ensure that all specifications—such as size, pressure rating, and material—are correct for the application at hand and are compatible with the male counterparts being used. It is also important to note that while the GOST standard is widely used in Russia and some neighboring countries, it may not be compatible with hose fittings from other regions that use different standards such as the North American NST/NH or the European Storz coupling standards.
