Brand Name:
Carterberg
Certification:
IATF16949
Model Number:
CB-SP-6FN-PTR
The CB-SP-6FN-PTR from Carterberg is a compact, flat face hydraulic quick coupling engineered for tight-space, high-reliability applications. It is built from hardened steel and protected by a yellow zinc dichromate coating, ensuring strong corrosion resistance while remaining lightweight and compact in form.
This model integrates an anti-blowout bonded seal, a locking sleeve for pull-off prevention, and a dust-resistant protective structure—all within a design that is fully interchangeable with NITTO 350 Series couplers. It is ideal for mobile hydraulic systems requiring high reliability in constrained installation conditions, such as in electric power service vehicles or compact hydraulic tools.
| Feature | Description |
|---|---|
| Flat Face Non-Spill Valve | Minimizes fluid loss and air ingress during disconnection; ideal for clean, safe operations. |
| Mechanical Sleeve Lock | Prevents accidental pull-off or vibration-induced disconnection during equipment operation. |
| Dust Seal Protection | Outer sleeve structure prevents ingress of debris, protecting the locking mechanism and valve. |
| Anti-Blowout Bonded Seal | With PTFE backup ring to handle surge pressure without seal damage. |
| Yellow Zinc Coating | Offers improved corrosion resistance compared to standard coatings, while providing visible identification. |
| Steel Construction + Hardened Components | For mechanical durability in portable or vibration-prone environments. |
