Space Ocean and Enduralock to Standardize In-Space Fluid Docking Interface

Space Ocean, a leader in orbital logistics and in-space infrastructure, announced that it has entered into a Letter of Intent (LOI) with Enduralock, a trusted provider of advanced in-space servicing and assembly hardware for the aerospace and defense industries. The LOI outlines a strategic collaboration to integrate Enduralock’s OneLink docking interface into future Space Ocean platforms as a standardized in-orbit connection for fluid, data and power transfer.

As part of the agreement, Space Ocean intends to adopt Enduralock’s passive male receive port, which is available for Assembly, Integration & Test (AI&T) immediately, as a core interface across its fluid delivery and servicing ecosystem. The OneLink system enables secure transfer of power, data and fluids, and is designed to support significant axial loads, making it a key enabler for mission-critical operations such as refueling, resource offloading and modular infrastructure support. 

“The ability for spacecraft, stations, and service vehicles to connect seamlessly in orbit is foundational to building a scalable deep-space economy,” said Paul S. Mamakos, Founder and CEO of Space Ocean Corp. “Enduralock’s OneLink™ interface provides the mechanical, fluidic, and digital backbone to support those interactions making it possible for multiple actors to operate across a shared infrastructure layer.”

Enduralock, widely respected for its contributions to space-qualified fasteners and advanced mechanical systems, brings a proven track record to this collaboration. The company’s OneLink system enables plug-and-play interoperability across a range of mission profiles, from orbital labs and habitats to fuel depots and cargo haulers. 

“We’re excited to support Space Ocean’s vision for orbital logistics with a rugged, multi-function interface designed for long-duration use in space,” said Harold Hess, CEO at Enduralock. “Together, we’re making it easier for in-space assets to connect, deliver and refuel.”

The LOI is non-binding and outlines mutual objectives for technology integration, joint project evaluation and interface standardization across upcoming platforms. Discussions are also underway to explore co-development opportunities, mission-specific customization and feedback-driven enhancements. This collaboration marks another key step in Space Ocean’s commitment to building an open, interoperable and serviceable orbital infrastructure where logistics and power can flow across a growing space economy.
