Key Features
• ISO 7241 Series B dimensional compliance
• Self-sealing poppet valve for minimal fluid loss
• Ball-lock system for strong, secure retention
• Available in 304 or 316 stainless steel
• Thread formats: BSPP / NPT / SAE
• Suitable for high-corrosion environments and medium-pressure systems
Stainless Steel Material Options
The CB-SPL-1F coupling is available exclusively in 304 and 316 stainless steel, offering proven corrosion resistance across a wide range of hydraulic applications.
• 304 Stainless Steel is ideal for general-purpose fluid systems, industrial environments, and low-to-moderate corrosion risk areas.
• 316 Stainless Steel, with its higher molybdenum content, provides exceptional resistance to chlorides and harsh chemicals, making it the preferred choice for marine, chemical, and offshore use.
Both options ensure long-term durability, structural integrity, and consistent sealing under pressure.
