Symetrical couplings Guillemin
NF E 29.572 / NF EN 14420-8+A1

Raccords-symetriques-Guillemin

The Guillemin-coupling is a symetrical system and apt for a large variety of applications.

Its success is mostly because of the form, which enables perfect and easy closure.

Application areas for symetrical couplings Guillemin
Guillemin couplings are widely used for the transport of liquid or viscous hydrocarbons, bitumen included, chemicals or powders, except for liquefied gases and steam.
