Why Non-Threaded Couplers Like CB-SP3S-TC Are Ideal for High-Pressure Jacking Systems

Hydraulic jacking systems often operate in harsh, high-pressure conditions where safety, speed, and simplicity are paramount. Traditional threaded couplers, while robust, come with clear drawbacks: time-consuming connections, potential for cross-threading, and high failure risk under vibration. The CB-SP3S-TC offers a clean alternative—combining 10,000 PSI capability with a sleeve-lock, non-threaded design built for demanding hydraulic environments.

Common Problems with Threaded Couplers in Jacking Systems

Connection Under Load
• Threaded fittings can seize under residual pressure, making disconnection difficult or dangerous.
Risk of Cross-Threading
• Frequent connects/disconnects in field conditions can lead to damaged threads, leaks, or total failure.
Vibration Loosening
• High-pressure lifting often involves tool or platform vibration, which can cause threaded fittings to back off if not perfectly secured.

CB-SP3S-TC Structural Advantages

Sleeve Lock Mechanism
• Allows fast, secure connection without twisting or torque.
• Locks in place via ball mechanism—no chance of accidental loosening.
Positive Valve Stop
• Ensures consistent valve alignment and reliable flow cutoff with metal-to-metal sealing.
No Swivel = No Stress Points
• Non-rotating design avoids torsional fatigue or valve shift under stress.
Faster Operation
• Connects in seconds—even with gloves or oily hands—ideal for field use or emergency repairs

When to Use CB-SP3S-TC

You should consider CB-SP3S-TC if:

• You operate jacks or lifting systems at >7000 PSI;

• Equipment is used frequently in the field, with risk of contamination or misconnection;

• Vibration or shock-loading is common during hydraulic operation;

• There is limited space or time to connect fittings under load.
