AI Technical Summary
Existing pipe or hose fittings face issues with cutting ring assemblies falling out or being pushed out of the union nut due to shearing of compressible locking elements, leading to incorrect assembly and potential loss.
A functional nut design featuring a union nut with an internal thread and a cutting ring assembly that includes a radially deflectable ring element, which deflects inwardly during assembly to engage the internal thread's root, preventing the cutting ring assembly from falling out and ensuring secure retention.
The design securely holds the cutting ring assembly in the union nut, preventing accidental loss and ensuring correct assembly, even after machine pre-assembly, by using elastically deflectable elements that engage the thread root, thus enhancing assembly reliability.
