Product Introduction

• Structure: A spin-on canister-style filter with a durable blue steel housing, a high-efficiency dual-layer filtration media, and a transparent water collection bowl at the bottom. It features a threaded connection for secure installation, a drain valve for water removal, and directional flow indicators printed on the housing.

• Performance: The dual-layer media captures fine particulate contaminants (down to 5–10 microns) and efficiently separates water from fuel, preventing corrosion, injector wear, and microbial growth in the fuel system. The transparent bowl allows visual inspection of accumulated water for timely maintenance.

• Design: Directly interchangeable with original equipment separators, engineered for quick tool-free replacement and easy water draining to minimize maintenance downtime.

Core Function

1. Water Separation: Removes water from diesel fuel to prevent corrosion and damage to sensitive fuel injectors and pumps, which can cause poor engine performance and costly repairs.

2. Fine Contamination Filtration: Captures small dirt and debris particles that bypass the primary filter, ensuring clean fuel delivery to the injection system.

Why This Fuel Water Separator Matters to Your Business

Engineered Performance That Sells Itself

• High-Efficiency Water Separation: Multi-layer coalescing media captures water droplets as small as 10 microns, preventing corrosion damage to WEICHAI high-pressure common rail injection systems.
• Extended Service Life: Premium cellulose-synthetic blend filter media delivers up to 20,000 km service intervals under standard operating conditions — reducing your customers’ maintenance frequency and boosting repeat orders for you.
• Optimized Fuel Flow: Low-restriction design maintains consistent fuel delivery rates even as the filter element accumulates contaminants, eliminating power loss complaints.
• Corrosion-Resistant Housing Compatibility: Precision-machined sealing surfaces ensure leak-free installation on OEM filter housings without adapter modifications.
• Built-In Drain Valve Interface: Allows quick water drainage during routine checks, a feature fleet managers actively request.

Distributor-Focused Advantages

• Competitive MOQ Flexibility: Scalable order quantities designed for regional distributors testing new market segments or established wholesalers replenishing high-volume SKUs.
• Healthy Margin Architecture: Factory-direct pricing from China removes intermediary markups, giving you room to compete on price while maintaining 30–45% gross margins.
• White-Label Packaging Available: Launch your own brand identity with custom-printed boxes, labels, and documentation — no minimum design fees.
• Consistent Supply Chain: Dedicated production lines ensure 7–15 day lead times on standard orders with batch traceability documentation included.

Application Scenarios – Where This Fuel Water Separator Performs

The Fuel Water Separator 612600081335H WEICHAI is purpose-built for heavy-duty commercial vehicles and industrial machinery powered by WEICHAI diesel engines. Here are the primary application environments where this filter delivers measurable ROI:

• SINOTRUK HOWO A7 / T7H Tractor Units: Long-haul logistics fleets running WP10.375E50 engines depend on consistent fuel cleanliness across 2,000+ km routes where fuel quality varies station to station.
• SHACMAN F3000 / X3000 Dump Trucks: Mining and construction sites expose fuel tanks to moisture ingress from condensation and contaminated bulk fuel supplies. This separator prevents injector failures in high-vibration, dusty environments.
• FOTON Auman GTL Heavy Trucks: Equipped with WEICHAI WP12 engines for intercity freight, these vehicles require reliable water separation to maintain Tier-4 emission compliance and fuel economy targets.
• WEICHAI-Powered Generator Sets: Stationary power applications in tropical or coastal climates face extreme humidity levels that accelerate fuel contamination — making scheduled separator replacement a non-negotiable maintenance item.
• Construction & Agricultural Machinery: Wheel loaders, excavators, and tractors operating in remote areas often source fuel from mobile tankers with inconsistent filtration. This separator acts as the final quality gatekeeper before fuel reaches the engine.

If your customer base includes fleet operators, mining companies, or equipment rental firms managing WEICHAI-powered assets, this part number represents a recurring, high-demand consumable with predictable reorder cycles.

OEM/ODM Capabilities – Build Your Brand on Proven Quality

Quality Assurance You Can Verify

Every Fuel Water Separator 612600081335H leaving our facility undergoes rigorous inspection protocols:

1. Burst Pressure Testing: Each unit is tested at 2× rated operating pressure to verify structural integrity before packaging.
2. Flow Rate Validation: Random batch samples are tested on calibrated flow benches to confirm rated throughput specifications.
3. Material Certification: Filter media and seal compounds come with traceable material certificates from approved sub-suppliers.
4. Dimensional Inspection: Thread gauges and CMM checks ensure drop-in fitment with zero field returns due to compatibility issues.

Custom Packaging & Private Label Options

Client Case Study – Fuel Water Separator 612600081335H Driving Growth in East Africa

In Q3 2023, a Nairobi-based truck parts distributor approached METTLEAD seeking a reliable source for Fuel Water Separator 612600081335H WEICHAI units. Their existing supplier delivered inconsistent quality — approximately 8% field return rate due to premature seal failures and substandard filter media that allowed water bypass.

After receiving evaluation samples and conducting a 60-day field trial across 12 HOWO tractor units operating on the Nairobi–Mombasa corridor, results were clear:

• Field return rate dropped from 8% to under 0.5%.
• Fleet customers reported zero injector-related breakdowns during the trial period.
• The distributor’s reorder volume scaled from an initial 200 units to 1,500 units/month within two quarters.
• White-label packaging with their brand identity strengthened market recognition against competitors selling unbranded Chinese generics.

Today, this partner stocks 14 WEICHAI filtration SKUs from METTLEAD and has expanded into SINOTRUK brake and transmission categories — all sourced through a single logistics channel that simplifies their procurement workflow.

Frequently Asked Questions – Fuel Water Separator 612600081335H WEICHAI

What vehicles does the Fuel Water Separator 612600081335H fit?

This separator is designed for WEICHAI WP10, WP12, WD615, and WD618 diesel engines commonly installed in SINOTRUK HOWO, SHACMAN, FOTON Auman, and various Chinese-brand heavy trucks. It directly replaces the original 612600081335H unit without modifications.

How does this Fuel Water Separator perform compared to the OEM original?

Our 612600081335H meets or exceeds OEM separation efficiency (≥95% free water removal). The filter media grade, seal material, and bypass valve calibration are manufactured to original equipment specifications. Many distributors report lower field return rates compared to aftermarket alternatives.

What is the recommended replacement interval for this Fuel Water Separator?

Under standard highway operating conditions, replace every 15,000–20,000 km. In high-contamination environments (construction sites, regions with poor fuel quality), shorten the interval to 10,000–12,000 km. Always drain accumulated water from the separator bowl during routine daily or weekly checks.

Can water damage still occur if the Fuel Water Separator is installed correctly?

The 612600081335H removes free water and emulsified water particles down to 10 microns. However, dissolved water (below molecular separation thresholds) passes through all mechanical separators. For extreme-humidity applications, pairing this separator with an upstream pre-filter provides additional protection layers.

Is this Fuel Water Separator compatible with biodiesel or blended fuels?

The NBR seals and filter media are compatible with standard diesel and B5 biodiesel blends. For B20 or higher biodiesel concentrations, consult our technical team — seal material upgrades (FKM/Viton) may be recommended to prevent swelling and premature degradation.

How should I store Fuel Water Separator 612600081335H units in my warehouse?

Store in original packaging, upright, in a dry environment between 5°C and 35°C. Avoid direct sunlight exposure, which can degrade the rubber seal over time. Shelf life under proper storage conditions is 36 months from date of manufacture.
