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
