Product Description
Product Features
-
Structure: A three-piece set including a top compression ring (with a wear-resistant PVD coating), a second taper-faced compression ring, and a spring-loaded oil control ring with a scraper design.
-
Performance: Withstands extreme combustion pressures and temperatures up to 450°C, maintaining a tight seal between the piston and cylinder wall to minimize gas leakage and oil consumption. The advanced coating ensures exceptional wear resistance and longevity.
-
Design: Precision-machined to match the original MC13 piston and cylinder bore tolerances, ensuring a perfect fit and optimal sealing performance right out of the box.
Core Function
-
Compression Rings: Seal the combustion chamber, ensuring that high-pressure gases are contained to maximize power output and prevent blow-by into the crankcase.
-
Oil Control Ring: Scrapes excess oil from the cylinder wall, preventing it from entering the combustion chamber and reducing oil consumption and exhaust particulate emissions.
-
Maintains a thin, uniform oil film on the cylinder wall to lubricate the piston and reduce friction and wear.
Engineered for the demanding operating conditions of SINOTRUK MC13 diesel engines, the Mettlead Piston Ring Set 202V02503-6005 delivers OE-equivalent sealing performance, superior oil control, and extended service life. This precision-manufactured three-piece ring set is purpose-built for fleet operators, engine rebuilders, and parts distributors who need reliable aftermarket components without the OEM price tag.
Whether you manage a mixed heavy-truck fleet across Africa, Southeast Asia, or the Middle East, or you supply engine overhaul kits to workshops, this SINOTRUK piston ring set gives you the dimensional accuracy and material quality your customers demand — backed by Mettlead's strict quality control process and flexible packaging options.
Features & Benefits — Why Procurement Managers Choose Mettlead MC13 Piston Rings
1. Three-Piece Engineered Ring Set
- Top Compression Ring: Features a wear-resistant PVD (Physical Vapor Deposition) coating that dramatically reduces friction, resists scuffing, and maintains gas-tight sealing under extreme combustion pressures.
- Second Compression Ring: Taper-faced profile promotes rapid seating, efficient blow-by gas control, and consistent oil film scraping from the cylinder wall.
- Oil Control Ring: Spring-loaded design with a precision scraper geometry ensures optimal oil distribution while preventing excessive oil consumption — critical for reducing emissions and lowering operating costs.
2. Direct OEM Cross-Reference
Part number 202V02503-6005 is a direct replacement for the original SINOTRUK MC13 engine piston ring assembly. No machining, no modification — drop-in fitment for faster workshop turnaround.
3. Cost-Effective Fleet Maintenance
Mettlead's China-based manufacturing delivers 30–50% cost savings versus genuine OEM rings while maintaining the dimensional tolerances and material specifications required for reliable long-haul performance. For procurement managers balancing price and quality, this is the sweet spot.

Frequently Asked Questions — SINOTRUK Piston Ring MC13
Q1: Is this piston ring set compatible with all MC13 engine variants?
Yes. Part number 202V02503-6005 is designed as a direct-fit replacement for the standard SINOTRUK MC13 engine series. If you have a specific sub-model or build year concern, send us your engine nameplate details and our team will confirm fitment within 24 hours.
Q2: What is the advantage of PVD coating on the top compression ring?
PVD coating provides a micro-hard surface layer that resists wear, reduces friction against the cylinder liner, and prevents scuffing during cold starts or high-load operation. This translates to longer ring life and more consistent compression over the engine's service interval.
Q3: Can I order with my own brand and packaging?
Absolutely. Mettlead offers full white-label and custom packaging services. You provide your brand guidelines, and we deliver finished, retail-ready products to your warehouse. Minimum order quantities apply — contact us for details.
Q4: What is the typical lead time for bulk orders?
Standard lead time is 15–25 working days depending on order volume and packaging requirements. For urgent needs, we can discuss expedited production schedules. We recommend placing orders 4–6 weeks ahead of your restocking deadline.
Q5: How does Mettlead ensure quality consistency across batches?
Our quality control process includes incoming material inspection, in-process dimensional checks, surface finish measurement, and final ring gap verification before packaging. Each production batch is traceable, and we can provide inspection reports upon request.
Q6: Do you supply complete engine overhaul kits or only piston rings?
Mettlead specializes in Chinese brand truck components. Beyond piston rings, we supply cylinder liners, pistons, gasket sets, bearings, and other engine rebuild parts for SINOTRUK, Weichai, and related platforms. Ask our team about bundled kit pricing.
