Guillemin Symmetrical Half Coupling, Fire, Without Lock with Female Threaded Socket in Stainless Steel

The female threaded Guillemin symmetrical half coupling is a high-performance joining component, designed for rigorous integration on fixed installations or transfer pipework. This model is offered in its lockless version (without jaws), which means it must be coupled with an opposing coupling fitted with a locking ring to ensure the mechanical connection. Its symmetrical design allows for quick and intuitive connection, facilitating interventions on complex fluid networks.

AISI 316 Stainless Steel: Excellence for Aggressive Environments

Machined in CF8M AISI 316 (1.4401) stainless steel, this coupling offers exceptional resistance to corrosion and chemical attack. This superior quality material is particularly recommended for sectors where hygiene and material inertness are critical, such as the pharmaceutical industry, food processing and sugar refineries. Its structural robustness guarantees maximum longevity, even when transporting corrosive liquid bulk materials or abrasive powdered substances.

Normative Compliance and 16 Bar Performance

This coupling strictly complies with standards NF E 29.572 and NF EN 14420-8, ensuring perfect interchangeability with all standard Guillemin half couplings on the market. Rated for a working pressure of 16 bar, it meets the most stringent safety requirements for firefighting or industrial maintenance operations. Its BSP (Gas Thread) female thread allows reliable mounting on valves, manifolds or male threaded outlets.

Application Versatility: Suction and Discharge

Thanks to its mechanical properties and thermal resistance, this half coupling can be used with equal efficiency in suction and discharge applications. It finds its place in an extremely wide range of fields, from intensive agricultural irrigation to steelworks, including petroleum and petrochemical industries. Its versatility makes it a reference solution for the transport of various fluids in the construction and industrial logistics sector.

Assembly and Sealing Advice

For mounting the threaded part, the use of a suitable sealing product (PTFE tape or hemp depending on the application) is recommended to secure the fixed connection. For the symmetrical coupling, present the fitting face to face with its opposite equipped with a lock, ensuring the seals are in proper contact. Engage the lock manually. To guarantee optimal safety, particularly under conditions of vibration or fluctuating pressures, we recommend finalising the locking of the opposing lock using a suitable Guillemin key.
