The french hose couplings are symmetrical, clamp fitting and hose tail are one piece fitted with a locking ring. By turning the locking ring the bosses are pushed underneath the two strips of the mating coupling (1).
The adapters and blank caps are available with and without locking ring, in order to connect with hose couplings or mutually only one locking ring is required for connection (2).
DSP couplings (3a) are used for pressure-, AR couplings for suction purposes in the fire fighting field. Guillemin couplings (3b) are used for pressure- and suction operation in all other sectors. Both types differ by the preformed bosses on the locking ring resp. the strips on the lugs (3).
Identical sizes of the two coupling types can be coupled together.
Mind the illustrated assemble of adapters with or without locking ring on the equipment.
