GUILLEMIN REDUCTION WITH CLOSURE
Guillemin reducer with lock
A Guillemin reducer with a locking mechanism is a type of fitting used to join two pipes or tubes of different diameters. It is characterized by its symmetrical design and airtight sealing system, making it ideal when a high degree of safety and reliability is required. It is ideal for transferring fluids and powdered materials.
Applications: Chemical and petrochemical industry, Food and pharmaceutical industry, Textile industry, Construction, Agriculture, Mining
Main features:
- Symmetrical guillemin fitting.
- Max. pressure 16 bar.
- BSPP type threads (cylindrical)
- Gasket included in NBR (see other materials)
- Available in INOX-316 steel and aluminum (other materials available upon request)
Guillemin reducer with lock
A Guillemin reducer with a shut-off fitting is a quick-connect fitting for hoses and pipes, based on the Guillemin coupling system , which allows two pipes of different diameters to be joined and the flow of fluid to be safely shut off when not connected to another fitting or hose.
The Guillemin system is a symmetrical quick-connect coupling, widely used in industry, chemical, agricultural and fire protection , which allows coupling between two identical fittings using claws and a safety ring, without the need for tools.
Materials
- Aluminum or stainless steel
- NBR sealing gasket that guarantees a hermetic seal
Applications
- Transfer of industrial liquids
- Chemical and petrochemical systems
- Water, irrigation and fire protection networks
