Screw-to-Connect 

Screw-to-connect quick couplings are designed for high-pressure and high-flow applications. Unlike push-to-connect couplers, these require manual threading to establish a secure and leak-proof connection. While they take more time to connect and disconnect, they provide superior holding strength and stability under extreme conditions. As a result, they are widely used in heavy-duty hydraulic equipment, construction machinery, and industrial applications where reliability is critical.
