RMG-4-FSD — 4-Contact Rubber Moulded Dummy Connector

The RMG-4-FSD is a 4-contact rubber-moulded dummy connector — a female-socket dummy cap that protects male-pin faces (RMG-4-MP in-line, XSG-4-BCL bulkhead). Moulded in special neoprene with hard gold-plated contacts, it keeps the unmated face sealed and the contacts protected during deck handling, water entry and storage.

RMG-4-FSD 4 Contacts Dummy / Protective Cap HP & LP Versions Marsh Marine Style

Key Design Features

  • Protective cap: seals the unmated connector face against water, mud and mechanical damage.
  • Pressure-rated options: HP (high-pressure, to 20,000 psi mated) and LP (low-pressure, to 4,000 psi) variants — select to match the working locking sleeve.
  • Marsh Marine style: mates with RMG/RMK faces of the opposite contact type; inter-mateable between brands in this category.
  • Gold-plated contacts: copper alloy, hard gold plated per ASTM-B-488 — maintains the contact system when mated.
  • Neoprene moulded body: flexible, impact resistant, glove-friendly for deck handling.

Typical Applications

Protective capping for diver umbilical connectors, helmet and mask connectors, dive bell and dive basket panel bulkheads, and any unmated RMG/RMK face during diving operations, deck handling and storage.

Notes for Selection

Select the dummy gender to match the face being protected: female-socket dummies (FSD) cap male-pin connectors, male-pin dummies (MPD) cap female-socket connectors. Order the HP or LP variant to match the locking sleeve in service, and specify -S for stainless-steel hardware where required. Store connectors with dummies installed, dry and UV-shaded.

Custom configurations available Other contact counts, stainless-steel hardware and custom pigtail dummies can be specified to order. Send us your requirement for a quotation.
