    DSP and AR resemble NF Guillemin couplings in that DSP are used for pressure, AR for suction purposes in firefighting field; Guillemin for general industrial use.

    The lock mechanism (LK - locking ring) is made on both or either of the coupled sets.

    Required shape of hose shank can be made, as the ribbed tail for band-clamping assembly.
