CB-SP2S-TF vs CEJN 115/116 Series: What Compatibility Really Means

Why Compatibility Matters in Super High Pressure Systems

When working with systems that push the boundaries of pressure—up to 21739 PSI—connection failure is not an option. Many engineers and purchasing teams using CEJN 115 or 116 series couplers seek cost-effective, lead-time-efficient alternatives. But is "compatible" really enough?

Let’s unpack what compatibility means when it comes to CB-SP2S-TF, Carterberg’s precision-engineered alternative to CEJN.

Dimensional Compatibility: Engineered to Fit

CB-SP2S-TF is dimensionally designed to match the interface of CEJN 115 and 116 Series quick couplings:

•  Thread Type: Same as CEJN – supports seamless connection

•  Coupling Interface Geometry: Fully matched to CEJN profiles

•  Locking Mechanism: Ball-lock structure with identical engagement stroke

•  Valve Arrangement: Equivalent poppet design for consistent open/close actuation

Result: CB-SP2S-TF can be connected directly to CEJN 115/116 couplers without requiring adaptors or special interface sleeves.

Seal Materials & Environmental Fit

CEJN typically uses FPM (Viton) or EPDM seals depending on temperature or media. CB-SP2S-TF is supplied standard with NBR, but offers optional upgrades upon request.

Working Temperature:
CB-SP2S-TF: -30°C to +100°C
CEJN 115: -30°C to +150°C (depending on seal type)

Note: For applications above 100°C or involving synthetic fluids, simply specify your seal preference when ordering CB-SP2S-TF.

Common Questions

Q: Can I use CB-SP2S-TF with an existing CEJN socket?
A: Yes, the geometry matches. However, for optimal sealing performance and long-term durability, we recommend replacing both halves.

Q: What seal materials are available?
A: Standard is NBR. You may request Viton or EPDM depending on your application’s chemical or thermal needs.

Q: Is this suitable for rescue tools or torque equipment?
A: Absolutely. CB-SP2S-TF was engineered specifically for extreme pressure, compact-size applications like hydraulic jacks, cutters, spreaders, and torque tensioning systems.
