Description
This is a DN 80 Guillemin coupling with G 3'' female threads. It is made of aluminium with an NBR seal. The maximum pressure is 16 bar (232 psi). The coupling is suitable for temperatures between -10 to 80 °C (14 to 176 °F). Not equipped with a lock ring. A coupling with Gout a lock ring is often chosen on fixed installations.
The couplings adhere to NFE 29572 and EN 14420-8. Two identical couplings are joined by interlocking the jaws and turning the lock rings. Use a Guillemin wrench for sufficient closure.
Note: At least one of the two couplings needs to have a locking ring and only versions with locking rings have a soft seal. Typically, the fixed coupling (i.e. on a tank) won't have a locking ring and the other coupling (i.e. on a hose) will have a locking ring and soft seal.
Pros:
- Simple and easy connection
- Large free flow area
- Aluminum couplings are lighter in weight than stainless steel
- Suitable for water, fluids, hydrocarbons, chemicals, and dry loose materials
Cons:
- Not suitable for steam and other gases
- It does not have a locking ring and soft seal, so it needs to be coupled to one with that feature
