Product Introduction: A high-strength, corrosion-resistant plastic connector with integrated mounting clips for secure installation. It features a smooth internal surface to minimize airflow resistance and a tight-seal design to prevent leaks. The robust plastic construction withstands vibration and temperature fluctuations in the engine compartment.

Function: Connects the air-fuel separator to the vehicle’s ventilation system, ensuring separated crankcase gases are recirculated back to the engine intake. This helps maintain proper crankcase pressure, reduce emissions, and prevent oil vapor from escaping into the atmosphere.

Connector-Air Fuel Separator 200V98130-0549 SINOTRUK – OEM Crankcase Ventilation Fitting for MC11/MC13 Engines

Every heavy-duty engine relies on its crankcase ventilation system to manage blow-by gases — and the connector linking that system together matters more than most people realize. The Connector-Air Fuel Separator 200V98130-0549 is a SINOTRUK OEM pipeline fitting designed to join the oil-gas separator to the crankcase ventilation circuit on MC11 and MC13 engines. Once it degrades or cracks, pressure starts building in places it shouldn’t, seals begin to weep, and before long you’re dealing with unplanned downtime across your fleet. That’s exactly why JINAN METTLEAD AUTO SALES CO.LTD. keeps this part available at factory-direct pricing with strict quality checks — helping you stay ahead of failures instead of reacting to them, while keeping maintenance costs where they belong.

Key Functions & Benefits of the 200V98130-0549 Connector

Precision-Engineered for Oil-Gas Separation Circuits

This connector serves as the interface joint between the air fuel separator (oil-gas separator) housing and the crankcase ventilation hose on SINOTRUK heavy-duty diesel engines. It ensures a leak-free, vibration-resistant seal under the extreme thermal cycling and pressure fluctuations typical of long-haul and construction-site duty cycles.

• Maintains Crankcase Pressure Balance – Prevents excessive positive crankcase pressure that accelerates seal degradation and oil consumption.
• Resists Thermal Fatigue – Engineered to withstand continuous exposure to hot blow-by gases (150 °C+) without cracking or deforming.
• Vibration-Dampening Fit – Tight-tolerance molding absorbs engine vibration, eliminating micro-leaks that plague aftermarket alternatives.
• Plug-and-Play OEM Replacement – Drops directly into the original mounting position with no modification, reducing workshop labor time to under 15 minutes.
• Extends Separator Service Life – A properly sealed connector prevents unfiltered air ingress that contaminates the separator element prematurely.

Application Scope

The 200V98130-0549 connector is designed for the following SINOTRUK platforms equipped with MC11 (10.5 L) and MC13 (12.9 L) engines meeting China V / China VI emission standards:

• SITRAK C7H / G7 – Long-haul tractor units
• HOWO T7H / TX – Heavy-duty logistics and construction trucks
• HOWO A7 – National V/VI compliant models with MC-series engines
• SINOTRUK Mining Trucks – Off-highway applications requiring robust crankcase ventilation

No matter where your trucks are running—African highways, Southeast Asian job sites, or freight corridors across Central Asia—this connector brings the same factory-grade reliability it had the day it was manufactured.

Frequently Asked Questions (FAQ)

What exactly does the Connector-Air Fuel Separator 200V98130-0549 do?

It acts as the sealed pipeline junction between the oil-gas separator (air fuel separator) and the crankcase ventilation hose on SINOTRUK MC11/MC13 engines. Without it, blow-by gases escape unfiltered, causing oil mist contamination and increased emissions.

Is this connector compatible with both China V and China VI engines?

Yes. The 200V98130-0549 is used across both National V and National VI variants of the MC11 and MC13 engine families. The crankcase ventilation routing is identical; only the calibration of the separator element differs between emission tiers.

How do I know if my connector needs replacement?

Look for these symptoms: visible oil seepage around the separator housing, excessive crankcase pressure (dipstick blowing out), increased oil consumption without external leaks, or a cracked/brittle connector body during routine inspection. Recommended inspection interval: every 100,000 km or annual service.

Can this connector be installed without special tools?

Absolutely. The 200V98130-0549 uses a push-fit retention design with an O-ring seal. Installation requires only basic hand tools and takes approximately 10–15 minutes for a trained technician. No sealant or torque wrench needed.

What is the difference between this OEM connector and aftermarket alternatives?

OEM connectors are manufactured to SINOTRUK’s exact dimensional and material specifications (typically PA66-GF reinforced polymer). Aftermarket copies often use lower-grade plastics that become brittle under thermal cycling, leading to premature cracking and costly re-repairs. Our supply chain sources directly from SINOTRUK’s authorized component manufacturers.

What is the minimum order quantity (MOQ)?

We offer flexible MOQs — from single-piece sample orders for fitment verification up to container-load quantities for wholesale distributors. Contact our sales team for tiered pricing based on your volume.

How is the connector packaged for international shipping?

Standard orders ship in original SINOTRUK branded packaging. White-label and custom packaging options are available for orders above agreed thresholds. All shipments include moisture-barrier inner bags and foam cushioning to prevent transit damage.
