RMG-2-FS — 2-Contact In-Line Rubber Moulded Diving Connector

The RMG-2-FS is a Marsh Marine style in-line rubber-moulded subsea connector (2 contacts, female (sockets)) purpose-built for commercial diver umbilical communications, underwater cameras, lighting and instrumentation. The special neoprene body is moulded directly onto a 18/2 AWG SOOW pigtail, with hard gold-plated contacts per ASTM-B-488 and a visual index in-line with contact #1. Marsh Marine style connectors are inter-mateable between brands in this category.

RMG-2-FS 2 Contacts Female 600 V DC Up to 20,000 psi Mated Diver Umbilical Comms Marsh Marine Style

Key Design Features

  • Purpose-built for commercial diving: flexible rubber body, push-to-mate geometry and tool-free locking sleeve designed for use with thick diving gloves.
  • 600 V DC contacts: copper-alloy contacts hard gold plated per ASTM-B-488 for low, stable contact resistance in seawater service.
  • Up to 20,000 psi mated: with high-pressure (HP) locking sleeve the mated pair is rated to 20,000 psi (approx. 13,000 m); low-pressure (LP) sleeves are rated to 4,000 psi.
  • Inter-mateable: Marsh Marine style RMG/RMK faces mate with most major brands in this category, so existing umbilicals and helmets need no re-termination.
  • Visual index in-line with contact #1: fast, error-free orientation on deck and in low visibility.
  • Complete system: matched MP/FS counterparts, G/K locking sleeves and HP/LP dummy plugs available from one supplier.

Typical Applications

Diver umbilical communications and extension cables, helmet and mask connections, bell and saturation diving umbilical joints, underwater cameras, lighting and instrumentation, hot-water suit umbilicals and IMCA-compliant DSV diving spreads.

Notes for Selection

Locking sleeve required. Always install the correct locking sleeve after mating (G-FLS-D for this connector; -S suffix for stainless steel). High-pressure (HP) versions are rated to 20,000 psi mated, low-pressure (LP) versions to 4,000 psi — select the sleeve and dummy to match the application depth. Install the dummy plug before water entry, rinse with fresh water after every seawater exposure and lubricate O-rings before storage.

Used for diver umbilical communications; underwater cameras, lighting systems and instrumentation.

Custom configurations available Cable type and length, contact count, right-angle (R/A) female versions and Gripper-style ruggedised bodies can be specified to order.
