Product Description

Carterberg CB-RK-SPM Thread-to-Connect Hydraulic Coupling

Flat-Face Valve | Residual Pressure Connect | Anti-Spill Design | Zinc Plated Steel

The Carterberg CB-RK-SPM is a thread-to-connect hydraulic quick coupling built for high-performance systems requiring clean disconnection and residual pressure compatibility. Designed with a flush-face valve structure and hardened threaded sleeve, this coupling ensures secure operation under demanding flow and impulse conditions — without the risk of fluid spillage. It is fully compatible with Stucchi VR and Voswinkel RK series, offering seamless interchangeability across various applications.

Key Features

• Flush-Face Design for No-Spill Performance

Valve interfaces seal tightly during connection and disconnection to prevent leakage or fluid loss.

• Residual Pressure Connect/Disconnect

Rated for up to 10 MPa (1450 PSI) residual pressure from either side — ideal for pressurized hydraulic systems in critical environments.

• Threaded Sleeve Locking Mechanism

Uses a steel sleeve with internal threads, providing secure mating with male thread fittings and strong resistance to vibration and separation.

• Zinc Nickel Plating for Corrosion Resistance

Advanced surface treatment ensures long-term anti-rust protection in harsh outdoor or mobile equipment settings.

• Valve Stop with Alignment Guard

Special valve stop retainer guarantees precise axial alignment and reliable sealing during use.
