Half symmetrical fitting Guillemin, firefighter, no male stainless steel threaded socket lock

The Guillemin Symmetrical Half Coupling for Male Screw-On is a high-precision industrial connection piece, designed for direct integration into fixed installations or pumping equipment. This model comes in its non-latched configuration (without jaws), which makes it suitable for coupling with an opposing coupling with a locking ring. Its symmetrical design allows for fast, indiscriminate connection of direction, maximizing the efficiency of field operations.

AISI 316 stainless steel: Superior thermal and chemical resistance

Machined from CF8M AISI 316 (1.4401) stainless steel, this fitting offers exceptional durability against the most aggressive corrosive agents. This high-end material makes it indispensable for demanding sectors such as the food industry, pharmaceuticals or petrochemicals, where hygiene and chemical inertia are paramount. Its robust structure allows it to withstand intensive service conditions while ensuring maximum longevity without the risk of oxidation contamination.

Standards Compliance and Hydraulic Performance

This fitting strictly complies with the NF E 29.572 and NF EN 14420-8 standards, guaranteeing total interchangeability with all Guillemin half-fittings on the market. Designed for a working pressure of 16 bar, it ensures optimal safety during the transfer phases. Its "Gas Pitch" (BSP) male thread allows hermetic mounting on manifolds, valves or pump outlets, withstanding suction and discharge stresses with equal reliability.

Assembly and sealing advice

For the installation of the threaded part, we recommend the use of a suitable sealant (PTFE tape or filasse depending on the application) in order to secure the connection with the threaded substrate. For the symmetrical coupling, present this half-fitting in front of a fitting with a lock, make sure the joints are in contact, and then operate the lock manually. For enhanced security in industrial environments subject to vibrations, the use of a Guillemin key is recommended to finalize the locking of the opposite lock.

Versatility for industrial use

Its robustness and thermal resistance open the doors to a wide variety of sectors: from firefighting to intensive agriculture, including steel mills and the transport of liquid or powdered bulk. Its CF8M stainless steel design is specifically adapted to maintenance and construction requirements where the safety and purity of the transferred products are essential. It is the reference equipment for corrosive work environments requiring reliable equipment that complies with European safety standards.
