FCR1504M 1500 Series Flange-Mounted 4-Pin Male Stainless Steel Underwater Connector

FCR1504M 1500 Series Flange-Mounted 4-Pin Male Stainless Steel Underwater Connector. Stainless steel underwater connector by RV POWER GROUP. 316L stainless steel body, IP68 rated, flange or bulkhead mount. Ideal for ROV, subsea, offshore energy and naval applications. Bulk pricing available.

FCR1504M 1500 Series Flange-Mounted 4-Pin Male Stainless Steel Underwater Connector

The FCR1504M is a 4-pin male flange-mounted subsea electrical connector from RV POWER's Metal Shell 1500 Series. Constructed from 316L stainless steel with precision-machined gold-plated contacts and molded O-ring seals, the FCR1504M delivers reliable electrical performance in demanding underwater environments — from shallow coastal to full ocean depth. The 4-pin configuration supports power + signal or dual-power circuits in ROV frames, subsea junction boxes, and offshore equipment. The flange-mounting interface provides superior vibration resistance vs. bulkhead designs.

Stainless Steel Metal Shell vs. Anodized Aluminum

The FCR1504M's 316L stainless steel shell outperforms aluminum connectors in long-term seawater deployment:

  • Superior seawater corrosion resistance — no anodizing layer to degrade
  • High mechanical strength — absorbs thruster vibration without distortion
  • Non-magnetic — critical for acoustic and magnetic sensing applications
  • No surface treatment required — ready for deployment straight from the box
