CB-SPL-10F Technical Specifications & Performance Data
Dimensional Overview (ISO-Compliant Geometry)
CB-SPL-10F conforms to the geometry standards set by ISO 7241-1 A, ensuring seamless fit across global hydraulic systems. Below are the dimensional characteristics by size:
| ISO Size | Nominal Diameter (mm) | L1 (mm) | L2 (mm) | Ø1 (mm) | Ø2 (mm) | F (Thread) | Weight (g) |
| 1/4” | 6.3 | 68 | 36 | 25 | 19 | G 1/4 / NPT 1/4 | 94 |
| 3/8” | 10 | 76 | 41.5 | 30 | 23 | G 3/8 / NPT 3/8 | 139 |
| 1/2” | 12.5 | 91 | 49 | 38 | 27 | G 1/2 / NPT 1/2 | 238 |
| 3/4” | 20 | 110 | 61.5 | 48 | 35 | G 3/4 / NPT 3/4 | 484 |
| 1” | 25 | 128 | 71.5 | 53 | 41 | G 1 / NPT 1 | 670 |
All measurements refer to the socket half in connected position.
Operating Pressure & Flow Data
Each size delivers pressure-optimized performance with minimal pressure drop at standard oil viscosity. Values below are based on 30 cSt hydraulic oil at 40°C.
| ISO Size | Max Working Pressure (bar/psi) | Flow Rate (Δp = 1 bar) | Spillage (ml) |
| 1/4” | 315 / 4565 | 6.3 l/min | 0.35 |
| 3/8” | 315 / 4565 | 10 l/min | 1.5 |
| 1/2” | 250 / 3625 | 12.5 l/min | 2.6 |
| 3/4” | 250 / 3625 | 20 l/min | 8.5 |
| 1” | 200 / 2900 | 25 l/min | 13 |
Flow Rate vs. Pressure Drop Curves
The following curve represents average flow performance for the CB-SPL-10F series under ISO testing conditions. Values may vary based on oil type and system restrictions.
Material & Seal Configuration Options
CB-SPL-10F allows flexible selection of materials and seals depending on application exposure (temperature, chemical compatibility, system pressure).
| Component | Standard Material | Optional |
| Body / Sleeve | Zinc-plated steel (Cr6-free) | Stainless steel on request |
| Valve | Zinc-plated steel | – |
| Balls | Stainless steel | – |
| Springs | Carbon steel | Stainless steel |
| Seals | NBR (nitrile) | FKM (Viton) |
Temperature Range:
• NBR: -20°C to +100°C
• FKM: -20°C to +200°C
Push-Pull Variant (1/2”)
CB-SPL-10F is available in a push-pull variant (bulkhead sleeve design) for 1/2” size, enabling automatic connection/disconnection by simply pushing or pulling the plug.
Commonly used in panel-mounted equipment or quick-release hydraulic tools.
Engineering Selection Notes
• Use NBR seals for standard mineral oils and temperatures under 100°C
• Upgrade to FKM in high-temp environments or synthetic oils
• Avoid high surge flow near rated pressure, especially in disconnected state
• Specify thread type clearly (G or NPT) when ordering to ensure compatibility
• For push-pull installations, confirm required panel cutout and sleeve length
