The Next Frontier in Quick-Disconnect Fluid Couplers

Calloway Advanced Technologies is pioneering the HALO (Hand-Actuated Locking Omni-seal, patent pending)—a novel high-pressure quick-disconnect fluid coupler for the aerospace, defense, and other high-consequence industries. The HALO differentiates itself from the market by its ruggedized architecture, leak-proof seal, absence of failure-prone polymer components, ability to be hand-operated without specialized tools, compatibility with all industry-standard fluids, and high cycle life.

Cryogenic Connectivity Technology

Engineered for Extremes

Calloway Advanced Technologies engineers next-generation fluid transfer systems for high-performance defense, air, and space applications. Based in Walton, KY, we specialize in coupling technology designed for fuel transfer, hydraulics, and cryogenics. Our flagship technology, HALO, utilizes aerospace-grade active metal sealing to eliminate leakage in critical fluid transfer operations. Whether operating on fighter-jet hydraulics or feeding cryogen to a quantum supercomputer, Calloway will be the trusted name across industries for reliable fluid transfer.
