CB-SPB-3FN Threaded Hydraulic Coupling – Brass Body, Dry-Break Design

CB-SPB-3FN is Carterberg’s brass-body threaded quick coupler, engineered for hydraulic fluid transfer in municipal vehicles, on-road systems, and general low- to mid-pressure applications.
Featuring a tubular dry-break valve and threaded locking structure (available in wing nut or hex nut configuration), this series allows secure connections even under back pressure conditions—up to 500 psi residual. The internal valve system minimizes fluid loss and air inclusion, helping maintain system efficiency and environmental safety.

Key Features

•  Threaded Latch Connection
Provides vibration resistance and safe coupling even with trapped pressure (up to 500 psi).
•  Dry-Break Tubular Valve Design
Significantly reduces fluid loss during disconnection—protecting system integrity and workplace safety.
•  Brass Construction + Hardened Components
Corrosion-resistant brass body with zinc-plated steel valving and threads.
•  Seal Material
Standard Buna-N for petroleum fluids; Viton and EPDM available on request.
•  Available in Wing Nut or Hex Nut Interface
Flexible configuration for panel mount or field operations.

Application Scenarios

CB-SPB-3FN is ideally suited for:
•  Municipal & Utility Service Vehicles
•  Waste Collection and Refuse Hydraulics
•  Bulk Liquid Transfer Systems
•  Construction Site Tool Connections
•  Agricultural Fluid Handling
This coupling is not intended for high-impulse industrial hydraulics. For mining or oilfield high shock systems, refer to CB-SPS-3FN series

Engineering Advantages

•  Threaded latch eliminates disconnect risk under vibration
•  Dry-break valve reduces downtime and clean-up
•  Low air inclusion preserves actuator precision
•  Low torque connect/disconnect for ease of use
