CB-SPS-3FM-B Thread-Lock Hydraulic Coupler (New Release)
New Product Launch | Currently Listed Under "New Arrivals"
The CB-SPS-3FM-B is Carterberg’s latest addition to its high-pressure coupler lineup. Featuring a precision-machined thread-lock sleeve and compact steel body, this model is designed specifically for portable hydraulic jacks and other extreme-pressure systems. As a newly released item, it is currently listed in our New Arrivals section and will be formally categorized under the "Thread-to-Connect" family following its launch phase.
Key Features at a Glance
• 10,000 PSI working pressure, ideal for ultra-high pressure circuits.
• Threaded sleeve lock ensures secure and vibration-resistant connections.
• Dual ball check valve design for reliable two-way shutoff.
• Hard-chrome steel body provides exceptional wear resistance.
• Compatible with Parker 3000 / Faster PVVM coupler profiles.
Structural Design Highlights
CB-SPS-3FM-B employs a mechanically threaded sleeve mechanism, where both male and female ends must be manually engaged and locked to activate the flow path. The locking threads are machined into the sleeve and nipple, forming a rigid, vibration-resistant union even under residual system pressure. Internally, hardened chrome steel balls are used for positive valve seating, ensuring leak-free shutoff on disconnection.
Seal integrity is maintained using NBR (nitrile rubber) as standard, allowing the unit to withstand petroleum-based fluids under intense pressure. The interface is engineered for precise alignment, minimizing fluid turbulence during flow transitions.

Recommended Applications
• Portable hydraulic jacks (rescue, lifting)
• Steel mill press tools
• Portable pressure testing units
• Aircraft ground support tools
• Other static or mobile high-pressure hydraulic circuits
This model is engineered for demanding field conditions where secure locking, compact size, and pressure tolerance are critical. It is particularly well-suited for portable and manually operated systems where vibration or residual pressure may pose a challenge to standard couplers.
Why This Model Matters
CB-SPS-3FM-B fills a unique gap in Carterberg's threaded coupler series. While other models are optimized for large flow rates or high-cycle use, this unit focuses on ultra-high pressure stability in a compact form factor. The threaded sleeve locking design minimizes the risk of accidental disconnection or backflow leakage—especially critical in hydraulic lifting tools, where personnel and equipment safety is paramount. Its compatibility with existing global coupler standards like Parker 3000 and Faster PVVM makes it a reliable drop-in upgrade for system integrators or OEM rebuilds.
Future Classification Plan
Once the early-stage performance validation concludes, CB-SPS-3FM-B will be integrated into Carterberg’s Threaded Hydraulic Coupling category, alongside other high-pressure variants such as CB-SPS-3FN-FD86 and CB-SPS-3FN-W26000. Until then, it remains discoverable under the New Arrivals section for easy access and customer feedback.
