Aluminium locking blanking cap with chain DN100

The symmetrical coupling, commonly known as a « fire brigade coupling », is a mechanical device for connecting two hoses. This system is used for the transfer of liquids or powders in the chemical, petrochemical and food industries, in irrigation and in firefighting. The two hoses to be connected are each fitted with a half-coupling.
A half-coupling consists of a body with a groove at the front containing the sealing gasket, two half-shells or jaws, a freely rotating locking ring with the ramps used for locking, and a retaining ring that holds the locking ring in position.

Complies with the French standard NF E 29-572
