Соединения DSP NF S61-704 / NF S61-705

STANDARD

DSP couplings are manufactured in compliance with NF S61-704 for the dimensions ND40 and ND65. The ND100 dimension is manufactured in compliance with NF S61-705

OPERATION

A DSP coupling is a self-sealing symmetrical coupling which is secured by interconnecting two DSP couplings. The half coupling is closed by turning the losking ring beneath the the triangular section of the opposed DSP coupling. Extra closure can be applied by locking the connection with LMC-Couplings patented multi wrench. The DSP coupling system is similar to that of the Guillemin coupling. There are howewer differences to the preformed serration on the locking ring and the design of the lugs. The locking ring of DSP couplings can be turned up to 45°.
