Carterberg CB-SPS-3F-BD Threaded Hydraulic Quick Coupling
Heavy-Duty Performance for Demanding Impulse Applications
The CB-SPS-3F-BD quick coupling from Carterberg is engineered for extreme conditions. With a thread-to-connect locking mechanism and robust steel construction, it offers reliable performance in mobile equipment, agriculture, and industrial systems that face high flow rates and pressure spikes.
Core Features
• Threaded Sleeve Locking
Manual thread engagement between socket and plug ensures a secure, leak-resistant connection under pressure.
• Anti-Impulse Valve Design
Internal valve structure resists hydraulic shock and high-frequency pressure pulses, protecting components and extending system life.
• Barstock Construction
Precision-machined from solid steel bar for maximum mechanical strength and wear resistance.
• Corrosion-Resistant Finish
Advanced plating process provides enhanced protection in outdoor and corrosive environments.
• System Compatibility
Fully compatible with FASTER VVS series couplers for seamless integration in replacement or expansion use cases.

Application Scenarios
The CB-SPS-3F-BD is designed for use in:
• Mobile Hydraulic Equipment – Tractors, excavators, drilling rigs
• Agricultural Machinery – Harvesters, irrigation control
• Industrial Systems – Hydraulic power units, cylinder actuation under dynamic loads
Its durability and resistance to surge pressure make it ideal for environments with frequent pressure cycling or high mechanical stress.
Why Choose CB-SPS-3F-BD?
Unlike standard flat-face or ball-valve couplers, the CB-SPS-3F-BD offers a mechanically reinforced threaded connection, which:
• Reduces connection failure due to vibration
• Handles residual pressure without fluid loss
• Extends service life in aggressive duty cycles
This makes it a dependable solution where safety, leakage prevention, and rugged use are top priorities.
