🔩 Secure your engine’s critical fluid connections with genuine SANY parts – the OEM assembled sealing element 160102130003A007 (Assembled Sealing Washer). This precision‑engineered sealing washer is a critical component within the SANY Engine Block Group. The 160102130003A007 assembled sealing washer provides a leak‑proof seal for oil galleries, coolant passages, and high‑pressure fuel connections on SANY D12 and D09 heavy‑duty diesel engines. When rebuilding your engine or performing maintenance, this genuine SANY washer ensures perfect compression, vibration resistance, and long‑term fluid containment in demanding construction, mining, and heavy transport applications.
The 160102130003A007 Assembled Sealing Washer is a precision sealing component within the SANY Engine Block Group. It appears alongside other critical parts: Pressure and Temperature Sensor, Cylinder Liners, Hexagon Flange Bolts, O‑rings, and dowel pins. Together, these form the foundation of SANY’s heavy‑duty diesel engines used globally in construction, mining, and transport.
The SANY D12 engine, jointly developed with DEUTZ, has a displacement of 12.12 liters and six cylinders. It delivers 360 kW (490 hp) at 1,900‑2,100 rpm, with maximum torque of 2,150 Nm. This high‑output engine requires robust sealing at every fluid interface to maintain performance and avoid leaks.
The D12 engine meets Euro VI emission regulations through its 1,800 bar common‑rail system. Its low idle speed of 525 rpm reduces component wear. Seal integrity prevents cross‑contamination between oil and coolant circuits, which would cause sludge formation and bearing failure. The 160102130003A007 maintains sealing force through thousands of thermal cycles.
Unlike a simple flat washer, the assembled sealing washer has a bonded elastomeric ring vulcanized to a steel or brass backing. When torqued, the elastomer compresses to a precise percentage of its original thickness, creating a consistent seal. The steel backing prevents extrusion under high hydraulic pressure, which can reach 10‑15 bar in oil galleries and up to 180 bar in fuel systems.
The 160102130003A007 uses FKM (fluorocarbon) for oil/fuel applications where high temperature resistance is needed (up to 200°C), or NBR for coolant circuits. The metal backing is zinc‑plated carbon steel or stainless steel for corrosion protection. Each lot is traceable and certified to SANY material specifications.
Critical engine locations such as the oil cooler bypass valve, thermostat housing, water pump mounting, fuel filter head, and high‑pressure pump mounting bolts depend on this washer to prevent leaks. A single failed washer can cause loss of fluid pressure, leading to overheating, oil starvation, or fuel contamination. In severe cases, a fuel leak creates a fire hazard, while an oil leak on a hot turbocharger can cause engine bay fires.
The D12 engine’s common rail system, split‑type cylinder head, and patented TOP‑Down cooling system all reduce energy consumption and noise. Each system relies on correctly torqued bolts with properly seated assembled sealing washers. The 160102130003A007 is used at oil cooler return lines, coolant distribution pipes, and fuel return fittings.
The D12 engine is widely applied in SANY truck mixers, dump trucks, truck‑mounted pumps, compact rollers, excavators, port machinery, and ultra‑high‑pressure pumps. Wherever these engines operate, the reliability of each fluid joint depends on using genuine SANY assembled sealing washers. Aftermarket washers may have incorrect hardness, wrong diameter, or poor bonding, leading to leaks.
Torque control is critical. When a bolt with an assembled sealing washer is tightened, the elastomer compresses to 15‑25% of its original thickness. Recommended torque for M8 bolts: 18‑25 N·m; M10: 35‑45 N·m; M12: 50‑65 N·m. Torque should be applied in one smooth motion to allow uniform settling. Over‑tightening crushes the elastomer beyond its elastic limit, causing permanent set and loss of seal. Under‑tightening leaves insufficient squeeze, causing immediate leakage.
Why the 160102130003A007 Assembled Sealing Washer Ensures Leak‑Free Engine Operation
Bonded Elastomer & Metal
The 160102130003A007 features a vulcanized rubber‑to‑metal bond that prevents elastomer shifting or extrusion under pressure, ensuring consistent sealing force even with oil pressure fluctuations.
High-Temperature Resistance
FKM elastomer withstands continuous oil contact at 150°C and short‑term peaks of 180°C. This maintains sealing properties even in the hottest engine areas such as cylinder head oil passages.
Chemical Compatibility
The 160102130003A007 resists diesel fuel, engine oil, ethylene glycol coolant, and hydraulic fluids. This broad compatibility makes it suitable for oil galleries, coolant passages, and fuel connections without swelling or shrinkage.
Genuine SANY Traceability
Each 160102130003A007 lot is traceable and certified to SANY material specifications. Aftermarket washers often lack this traceability and may use inferior rubber compounds that fail prematurely.
Technical Specifications – Assembled Sealing Washer 160102130003A007
Triple-seal design: The SANY D12 engine operates under extreme pressures. The 160102130003A007 assembled sealing washer replaces simple copper or fibre washers where higher reliability is required. When tightened, the elastomer lip compresses against the bolt shank and component face, creating a primary radial seal, a secondary axial seal, and a steel backing that prevents extrusion. This triple-seal design has been proven in SANY field tests to outlast conventional washers by a factor of three.
Sealing integrity requires correct torque, clean surfaces, and a new washer every time the joint is opened. Once compressed, the elastomer takes a permanent set and must not be reused. Aftermarket washers often lack the proper rubber‑to‑metal bond or correct Shore hardness, leading to leaks. During in‑frame overhauls, always replace every assembled sealing washer encountered. The 160102130003A007 may look reusable, but a new seal guarantees correct crush height and full effectiveness.
Installation requires clean mating surfaces. Inspect the washer for nicks, cracks, or delamination. Clean the bolt and flange area thoroughly. Position the washer so the elastomer lip faces the component (not the bolt head). The metal backing contacts the bolt head flange.
Apply assembly lubricant only if specified. For most applications, install dry to prevent over‑lubrication that could cause over‑torquing. Hand‑start the bolt and washer, then torque with a calibrated wrench. For multiple bolts (e.g., oil filter housing), follow the prescribed sequence.
Common errors: wrong washer size, reusing a compressed washer, cross‑threading, over‑tightening, and failing to clean surfaces. Any can cause immediate leakage or premature failure. A correctly installed washer shows a uniform rubber bead around the bolt head, indicating proper compression.
For severe conditions (mining, desert, high altitude), inspect assembled sealing washers for leakage every 1,000‑2,000 hours. If oil, coolant, or fuel is visible around a bolt head, replace the washer. Replacing all assembled sealing washers at major engine overhaul (10,000‑12,000 hours) is a cost‑effective preventive measure.

Failure symptoms and replacement criteria: Signs of a failed assembled sealing washer include fluid seepage around the bolt head, oil/coolant film on the engine block, a drop in fluid pressure without other cause, and dried residue attracting dirt. Replace the 160102130003A007 immediately if the elastomer is cracked, swollen, or separated from the metal backing. An over‑tightened washer may appear thinner with rubber extruded past the steel backing.
For severe service conditions, inspect washers every 2,000 hours. Always use a genuine SANY seal – generic washers lack bonded construction and will not provide reliable sealing. After installation, run the engine to full operating temperature and inspect for leakage. A small smear of residual lubricant is acceptable, but any active dripping is a failure.
To verify authenticity, inspect the 160102130003A007 for the SANY logo and part number molded into the rubber or stamped on the metal backing. Genuine washers have uniform appearance with full rubber‑to‑metal bonding and no flash. Aftermarket washers often have poor bonding, rough edges, or no markings. Always source from authorised SANY distributors.
When ordering, provide your engine serial number and the exact location (e.g., oil cooler mounting, thermostat housing, water pump stud). The 160102130003A007 is a standard sealing element for D12, D09, and D06 engines. All genuine SANY washers are supplied ready for installation; no additional sealants are required if surfaces are clean and torque is correct.
