  • FLUID COUPLINGS
    Publication number: 20260009485
    Abstract: Fluid handling couplings can include a main body with a front face and can define a longitudinal axis. Such fluid handling couplings can include a post extending parallel to the longitudinal axis, and a post receptacle. Fluid handling couplings can include a seal coupled to the main body around the longitudinal axis. A portion of the seal can protrude from the front face of the main body. Fluid handling couplings can include a removable membrane releasably attached to the front face of the main body and covering the portion of the seal protruding from the front face of the main body. Fluid handling couplings can be genderless, can include manually openable valves, and can be configured for single-use aseptic fluid handling usage.
    Type: Application
