CB-SP3S-TC Super High Pressure Hydraulic Quick Coupling | Parker TC Compatible
Carterberg’s CB-SP3S-TC is a purpose-engineered super high-pressure hydraulic quick coupling, designed to meet the extreme requirements of jacking equipment, rail maintenance tools, and lifting systems. Manufactured in carbon steel with hardened surfaces and sleeve-lock connection, this coupling delivers uncompromised safety, strength, and pressure handling up to 10,000 PSI. It is fully compatible with Parker TC series, ensuring system compatibility in high-pressure tool circuits.
Key Features & Benefits:
• Positive Valve Stop: Fixed perch design keeps valve alignment intact and enables full metal-to-metal valve contact, ensuring complete opening under rated pressure.
• Electrometric Sealing System: Provides reliable shut-off even under vibration and pressure shock, using precision machined components.
• Sleeve Lock Mechanism: Prevents accidental disconnection due to hose drag or vibration. Not suitable for swivel use.
• Durable Construction: Nipple, sleeve, and valve components are induction hardened for superior resistance to hydraulic impact and wear.
• Pressure Rating: Rated for 10,000 PSI (approx. 690 bar) working pressure.
• Flow Optimization: Designed for stable flow delivery at high pressure with minimal turbulence.
• Parker TC Compatibility: Functionally interchangeable with Parker TC series couplers.

Dimensional Overview
Applications:
• Hydraulic Jack Systems: Mobile lifting applications under high-pressure.
• Railway Equipment: Designed for heavy-duty maintenance tools.
• Construction: Jacking and shoring equipment where threaded couplers are prone to error.
• Industrial Maintenance: High-pressure systems requiring robust, safe coupling.
Product Comparison & Selection Guide: When to choose CB-SP3S-TC over other quick couplers:
• Use CB-SP3S-TC if your application involves lifting, jacking, or repetitive high-shock loads.
• For corrosive environments (e.g. marine, chemical), prefer stainless-steel variants like CB-SPM-10F-A.
• For general industrial use under 5,000 PSI, consider CB-SPL-10F as a cost-effective alternative.
FAQs
Q: Can CB-SP3S-TC be used in rotating systems?
A: No. This model is not rated for swivel applications. Rotation under pressure may damage sealing surfaces.
Q: Is this coupling interchangeable with Parker TC?
A: Yes, it is dimensionally compatible and functionally interchangeable with the Parker TC Series.
Q: What thread options are available?
A: NPT3/8” is standard. Other threads (BSPP, UNF) may be available upon request.
