Corrosion Isn’t a Spec — It’s a Threat
Most hydraulic system failures in marine or chemical environments
don’t start with pressure or flow — they start with corrosion. Over time, exposure to salt, humidity, or reactive fluids degrades
the integrity of a coupling, leading to pitting, seized threads, or
hidden leaks.
The CB-SPM-10F-A model, constructed from 316 stainless steel, is
specifically designed for corrosive applications where carbon steel
or plated brass simply doesn’t last.View full specifications and

Why 316 Stainless Steel?
316 stainless steel offers a superior level of resistance due to
its molybdenum (Mo) content, which dramatically enhances its performance in:
• Seawater and salt spray
• Acids and chlorides
• High-humidity outdoor storage
• CIP/SIP (clean-in-place/steam-in-place) environments
| Material | Corrosion Resistance | Chloride Resistance | Cost | Typical Use |
|---|
| Carbon Steel | Poor | Poor | Low | Industrial hydraulics |
| 304 SS | Moderate | Limited | Mid | Indoor fluid systems |
| 316 SS | Excellent | Excellent | High | Marine, food, pharma, chemical plants |
CB-SPM-10F-A uses full-body 316SS for both socket and plug halves — not just surface plating — eliminating hidden rust sources
inside the coupling.
Where Corrosion Happens (and How CB-SPM-10F-A Prevents It)
Common corrosion zones:
• External threads exposed to seawater mist
• Valve seats exposed to acidic cleaning fluid
• Coupler bodies installed near engines or chemical tanks
• Infrequently disconnected fittings with trapped moisture
CB-SPM-10F-A design response:
• Solid bar-stock machined 316SS: No thin-wall or cast parts
• Viton seals: Resistant to acidic and oil-based fluids
• Ball-lock retention system: Maintains mechanical integrity over time
• Push-to-connect valve mechanism: Reduces fluid ingress during coupling/decoupling
Industry Applications That Demand It
CB-SPM-10F-A is currently used in:
• Marine & offshore platforms: Anchor winches, deck systems, shipyard test systems
• Chemical dosing systems: Where traditional Buna-N fails
• Fire suppression systems: With glycol or nitrogen-rich fluids
• Refining and oilfield separation skids
• Food & beverage CIP lines: Where mild acids and steam are routine
• Agricultural and forestry equipment: Operating in wet, acidic soil environments
What to Look for in a Corrosion-Resistant Coupling
If you’re sourcing for a long-service, harsh environment, look for
these:
• 316 Stainless Steel Body (not plated carbon steel)
• Viton or EPDM seals (not NBR)
• Push-to-connect with shut-off valves
• Compatibility with Parker 6600, Hansen HA 15000, etc.
• Test rating at 1000–2000 PSI and 200°C
CB-SPM-10F-A checks every item — and backs it with real-world track
record in corrosive systems worldwide.
