SEACON-DS-0107 API Connectors

API Connectors

SEACON has historically adapted existing products to meet changing market needs. For decades, SEACON’s highly successful Metal Shell Series (MSS) connector range has offered high contact density and a variety of power and signal configurations to meet customer underwater power and data requirements. Adapted from that series, the SEACON API connector series complies with American Petroleum Institute (API) specifications 16D (Control Systems for Drilling Well Control Equipment and Control Systems for Diverter Equipment) and 17E (specification for Subsea Umbilicals).

API Connectors
API Compliant Connector Series


  • Bulkhead connectors are designed to be compliant with appropriate section of API 16D specifications
  • Cabled connectors and assemblies are designed to be compliant with appropriate section of API 16D and API 17E specifications
  • Redundant sealing at all pressure barrier interfaces
  • Multiple test ports for in-the-field o-ring testing and verification
  • Boot sealing in cabled connectors and assemblies in event of flooded cable conditions
  • Electrical, optical and hybrid connectors configurable in 8 shell sizes
  • Factory Acceptance Testing (FAT) includes both mated and open-face pressure testing
  • Custom interfaces available
  • Flanged Connector [bulkhead] Receptacle connectors have inboard water-blocking boots over the electrical termination to eliminate risk of failure in a flooded housing scenario
  • Pressure Balanced Oil Filled (PBOF) cables operate fully in the event of breached hose/water ingress with full-pressure water-blocking on the solder cup side of the connectors
  • Oil-filled cable connectors options available without valves eliminate a direct path for water to reach the face of the bulkhead connector in case of hose flooding
