Abstract: A coupling assembly is disclosed that includes a first member and a second member having a receiving portion sized to receive the first member. A retaining formation is provided on one of the first and second members. The retaining formation includes a ramp and two or more grooves, wherein each groove is at least partially defined by converging surfaces. A locking member is moveably secured in a cavity in the other of the first and second members. The locking member is configured to be moved in a first radial direction by the ramp upon movement of the first member into the second member.

Abstract: A coupling assembly includes a first coupling member that extends along an axis from a forward end toward a rearward end and includes a first locking surface and a first connection indicator positioned between the first locking surface and the rearward end. A second coupling member includes a receptacle for receiving the forward end of the first coupling member, an interior surface having a second locking surface and an exterior surface that may include a second connection indicator. A locking member is positionable between the first and second locking surfaces to connect the first and second coupling members. A release member is adapted to cover the first and second connection indicators when the locking member is positioned between then first and second locking surfaces and to expose at least one of the first and second connection indicators when the first and second coupling members are disconnected.

Abstract: The present invention includes a pre-assembled, high-pressure coupling interface adapter for use with a non-threaded port of a female member. The adapter comprises a generally cylindrically shaped metal body including a central longitudinal channel and an inner and outer surface. The body includes an external segment having an external end and an internal segment having an internal end, the internal segment configured for receipt within the port of the female member. The inner surface of the body is configured to engage and secure one or more external features of a separate male coupling member. The present invention also includes a coupling assembly including a coupling adapter and a method for forming a female coupling assembly including an adapter.

Abstract: A coupling assembly is provided comprising a first member and a second member. The first member includes an exterior surface having one or more engagement features. The second member includes a portion for receiving a portion of the first member having one or more locking features configured to mate with the engagement features of the first member to prevent rotation of the first member relative to the second member while connected thereto. When the first member is securely retained within the second member, the first and second members comprise a coupling assembly suitable for both low-pressure and high-pressure coupling applications. Further, depending upon the circumstances and intended environment, the second member may be configured with features for quick-connect and/or disconnect from a corresponding first member.
