The ZF 3217307023 O-Ring is an OEM elastomer seal for marine gearbox, hydraulic pump, and oil circulation interfaces in ZF transmission and cooler channels. Size: 30 mm inner diameter × 40 mm outer diameter × 4 mm cross-section, weight 0.11 kg (0.24 lbs). Hardness 70 Shore A for balanced flexibility and compression load retention. Operates in -40°C to +120°C (-40°F to +248°F) and tolerates high-pressure fluid systems up to 200 bar (2900 PSI) depending on elastomer compound (NBR/FKM/EPDM variants per application). Resistant to transmission oils, hydraulic fluids, fuels, ozone, and marine spray. Designed for long compression cycles, minimal swelling, and secure leak-free sealing in industrial and saltwater conditions.

ZF 3217307023 Heavy-Duty O-Ring Seal – Ø30×Ø40×CS4 mm for Marine Gearbox & Industrial Hydraulic Systems
Parameter Specification Brand / Manufacturer ZF (OEM) Part Number 3217307023 Seal Type Elastomer O-ring, static/dynamic sealing for oil and hydraulic junctions Dimensions Inner Ø: 30 mm (1.18 in), Outer Ø: 40 mm (1.57 in), Cross-Section: 4 mm (0.16 in) Weight 0.11 kg (0.24 lbs) Hardness / Durometer 70 Shore A Pressure Tolerance Up to 200 bar (2900 PSI / 2900 pounds per square inch) depending on compound Operating Temperature -40°C to +120°C (-40°F to +248°F) Elastomer Material Options - NBR (Nitrile) – best for transmission and hydraulic oils, fuels
- FKM/Viton – enhanced heat, oil & swelling resistance
- EPDM – spray, ozone & seawater resistance, non-petroleum coolants
Corrosion / Ozone / UV Resistance High resistance – safe for marine spray zones and open-air industrial seating Compression Set Resistance Typically ≤ 25% at 100°C for 24 h (compound dependent) Application Zones Gearbox pump seat, oil cooler ports, pressure plates, hydraulic manifold grooves Color Black (standard compound color; EPDM may vary to blue/green if specified in variant) OEM Compliance Meets ISO/ASTM quality standards, RoHS compliant per compound Service Replacement Interval Inspect every 6–12 months in marine use, replace if hardened/swollen or >25% compression loss is detected
Technical Benefits
- Maintains oil pressure stability in pump and cooler sealing groups
- Prevents oil leaks and air/water ingress in static and dynamic joints
- Balanced elasticity minimizes gap extrusion in 10–200 bar hydraulic sections
- Low swelling rate in transmission oils and petroleum-based service fluids
- Improves wear control and vibration-stress sealing endurance
- Direct OEM size ensures precise fit in sealing grooves without extrusion gaps
Installation & Service Notes
- Install into a clean, lubricated groove seat – static or dynamic manifold profiles
- Use light oil lubrication film for seating when interfacing with metal plates
- Do not twist during installation; ensure even compression on mating plates
- Follow gearbox or manifold torque sequence standards when compressed with plug or pump seats
Package Includes
- 1 × ZF 3217307023 O-ring seal
- Pre-packed OEM label for identification
- Bulk packs available on request when ordered in quantity
Precision OEM elastomer seal for high-duty marine gearbox, oil cooler, and industrial hydraulic manifolds where stable pressure retention and leak isolation are critical.
