• Rugged screw coupling connectors in high
corrosion resistant shells which are made
in nickel aluminum bronze alloy. The design
provides a very high reliability with dry mate
sealing down to 2.000 meters immersion
(deeper depth with special backshells). The M
marine connector series is approved by
VERITAS and LLOYD’S Register of shipping.
