Overview

French Hydrant Coupling Types
French hydrants use specific coupling standards:

Guillemin coupling (Symmetrical): Common in France, also known as "French coupling." Often sized DN65 or DN100 outlets, typically equipped with 2 symmetrical outlets.

Used for both suction and discharge hoses.

Symmetrical design: no male/female ends – both sides are identical.

Sizes: Typically DN40, DN65, DN80, DN100.

Connection: Coupled by engaging and rotating with a quarter-turn.

Locking: Often secured with locking rings or clamps for pressurized applications.

FAQ

Q: What are hydrant french coupling types?

French hydrant couplings are standardized connectors used in fire hydrants and hose systems in France. They allow firefighters to quickly connect hoses to hydrants or other firefighting equipment.

Q: hat is the most common French hydrant coupling type?

The most common is the Guillemin coupling (also called symmetrical coupling or DSP coupling in French standards). It's used widely in firefighting, industrial, and agricultural applications.

Q: What sizes are available for French hydrant couplings?

Typical Guillemin (DSP) sizes used in firefighting:

DN40 (1.5 inch)

DN65 (2.5 inch) – most common for firefighting

DN100 (4 inch) – for high-flow applications

Q: What materials are French hydrant couplings made from?

French hydrant couplings are commonly made from:

Aluminum (lightweight and corrosion-resistant)

Brass (durable and corrosion-resistant)

Stainless Steel (for harsh environments)

Q: How does a Guillemin (French) coupling work?

It is a symmetrical coupling with interlocking lugs. It connects by pushing the two halves together and twisting, often secured with a locking ring or lever.
