CB-SP-1F-SS Hydraulic Quick Coupling | Carterberg
The CB-SP-1F-SS is a precision-engineered ISO 7241-B quick coupling crafted entirely from 316 stainless steel, designed to perform reliably in high-temperature, aggressive fluid, and sanitary environments.
This model integrates a double shut-off poppet valve system and a ball-lock mechanism, ensuring secure, leak-free disconnection even under pressure. Its standard Viton seals provide excellent chemical and thermal stability.
Ideal for applications where fluid cleanliness, corrosion resistance, and thermal reliability are critical.
Key Features
• Fully meets ISO 7241-1 Series B dimensions
• Made from solid 316 stainless steel for superior corrosion resistance
• Double shut-off valve prevents fluid loss from both sides when disconnected
• Precision ball-lock retention system
• Standard Viton seals: compatible with hot oil, steam, solvents
• Clean connection/disconnection in demanding environments
• Available in BSPP, NPT, or SAE thread formats
