Guillemin symmetrical plug, firefighter, with stainless steel lock and chain

The Guillemin symmetrical plug with lock and chain is the essential safety accessory for hermetically sealing unused connection ports. Made from high-quality stainless steel, it provides total protection against the intrusion of foreign bodies, dust or moisture into your transfer circuits. Equipped with a movable locking ring, it guarantees impeccable mechanical strength, preventing accidental opening under the effect of residual pressure or vibration.

Stainless steel: lasting protection against corrosion

The use ofstainless steel gives this cap exceptional resistance to the most aggressive environments. Its inert structure is particularly well-suited to the requirements of the following sectors:

• The oil, chemical and petrochemical industries for storing corrosive fluids.
• The pharmaceutical and cosmetics sectors, to guarantee perfect tip hygiene.
• Agriculture and irrigation, where equipment is exposed to weather and fertilizers.

Reinforced safety with chain and lock

This cap has been designed for intensive use in the field, with no risk of loss or disconnection. Its retaining chain secures it to the fixed pipe or tank, preventing the accessory from getting lost during transfer operations. The cam locking system provides a compression seal, protecting your networks against :

• Leakage of liquid or powdery bulk residues after unloading.
• Internal oxidation of fixed piping during periods of inactivity.
• Accidental leaks at the discharge end if valves are mishandled.

Case studies

In a concrete fire-fighting application, this plug protects external water intakes against vandalism or the accumulation of garbage. For example, on a tanker truck transporting chemicals, the installation of chain plugs on each outlet valve is a basic safety measure to prevent environmental pollution. Its robustness also makes it indispensable in steel mills and on construction sites to protect suction and discharge manifolds.

Industrial maintenance and reliability

Thanks to its standard Guillemin symmetrical design, this plug instantly adapts to any half-fitting of the same nominal diameter. Stainless steel guarantees exemplary ease of cleaning and long service life, even when in frequent contact with powdery products or volatile liquids. Its airy, ergonomic installation enables operators to secure installations in a matter of seconds, optimizing maintenance times and reinforcing the overall safety of the production site.
