The VG2600110162 seal ring is not just a gasket—it’s a precision-engineered interface that ensures exhaust manifold integrity. Manufactured from heat-treated stainless steel with a resilient graphite overlay, it accommodates thermal expansion while maintaining a positive seal. Unlike conventional crush rings, the VG2600110162 features a spring-loaded internal geometry that compensates for flange distortion, making it ideal for high-mileage trucks operating in harsh climates. Fleet tests show a 27% reduction in soot leakage and a 12% improvement in turbo response when replacing worn rings with VG2600110162.

Installing the Exhaust Pipe Seal Ring is straightforward: clean the flange faces, apply a thin layer of anti-seize (optional), and torque the V-band clamp to 38–42 Nm. The seal ring self-centers, ensuring even compression. This part replaces OEM numbers 612630040060, 81.27401.0034, and directly cross-references to Howo A7, T7H, Sitrak C7H, and X6000 exhaust systems. Always verify your engine series—VG2600110162 is compatible with all Euro 5 and Euro 6 exhaust brake configurations.
In dynamometer tests, a new seal ring reduced exhaust gas leakage by 94% compared to a worn original seal. This translates to lower EGT (exhaust gas temperature), improved fuel economy by up to 3.8%, and a noticeable drop in cab noise. Drivers report sharper throttle response and reduced regeneration frequency on DPF-equipped trucks. The Exhaust Pipe Seal Ring also minimizes the risk of hot gas impingement on nearby wiring and sensors, protecting critical components.
Authentic rings feature a laser-engraved part number, a distinct dark grey graphite finish, and a 3‑point spring tensioner. The packaging includes a holographic Howo authenticity seal. Always source your Exhaust Pipe Seal Ring from authorized distributors to avoid counterfeit rings that can cause catastrophic exhaust leaks and turbo overspeed. Genuine parts come with a 12-month warranty against manufacturing defects.
Howo has been a leader in commercial vehicle components for over three decades. The seal ring is developed in the same R&D center that designs the company’s heavy-duty engines. Every batch undergoes 100% leak testing, dimensional analysis, and thermal cycling to guarantee zero-defect delivery. When you choose this seal ring, you’re not just buying a spare part—you’re investing in operational uptime and peace of mind.
The Exhaust Pipe Seal Ring is available as a single unit or in bulk service kits (10‑piece boxes). Bulk kits include installation lubricant and torque specification cards. For large fleets, we offer custom stock replenishment programs. Always refer to the latest parts catalog for supersession history—VG2600110162 supersedes earlier revisions with improved graphite bonding.
All technical data corresponds to the latest HOWO/Sitrak specifications. Part number VG2600110162 is subject to continuous improvement. Always confirm fitment using your vehicle VIN.
