is the definitive supercharger oil inlet pipe gasket engineered specifically for diesel engines. When you need absolute sealing integrity, this gasket eliminates oil seepage, maintains boost pressure, and extends turbocharger life. Designed as a direct-fit replacement, it matches the exact specifications of the component. For fleet operators and independent workshops, sourcing Howo/Sitrak truck parts is non-negotiable for reliability. The gasket combines heat-resistant composite materials with precision-cut geometry, ensuring a perfect mating surface between the supercharger oil inlet pipe and the engine block. Every application demands components that withstand extreme thermal cycling and vibration—this gasket delivers exactly that.
The supercharger oil inlet pipe operates under intense pressure and heat. A substandard gasket leads to oil weeping, boost loss, and potential supercharger failure. The gasket is manufactured with a multi-layer steel core coated with high-temperature fluorocarbon rubber, providing creep resistance. Unlike aftermarket copies, this gasket’s bore geometry precisely matches the oil passage, preventing flow restriction. Many workshops report that using the correct gasket reduces oil consumption and keeps the turbocharger vane mechanism clean.
Every dimension of the supercharger oil inlet pipe gasket is verified with optical comparators. The sealing bead is designed to provide uniform compression, even when flange surfaces show minor irregularities. This gasket’s FKM layer offers resistance to engine oil additives, diesel soot, and acidic combustion byproducts. For Howo and Sitrak trucks operating in extreme conditions—from Saharan heat to Siberian cold—the maintains its elasticity and sealing force.
To achieve optimum performance with the , clean both sealing surfaces thoroughly using a non-abrasive disc. Apply a thin film of clean engine oil to the gasket’s outer edge to ease positioning. Torque the retaining bolts to 25 Nm in a crosswise pattern, then re-torque after the first heat cycle. Never reuse an old gasket; always replace with a fresh . Inspect the oil inlet pipe for any burrs or scratches that could compromise the seal. Following these steps ensures that the delivers its full service life.
The gasket is interchangeable with several OEM part numbers used in Sinotruk and MAN-based engine platforms. It directly replaces the older design that lacked the FKM coating. Owners of Howo A7, Howo T7, Sitrak C7H, and Sitrak TGA series will find this gasket identical to the factory-fitted component. When ordering, always confirm that the part number reads to avoid mismatched bore sizes. This gasket is also backward-compatible with pre-2018 engine variants that use the same supercharger oil feed pipe.
Always verify with your vehicle’s VIN and engine serial number. Our reference fuel- data confirms that is the current production standard for all Howo and Sitrak trucks manufactured after 2016.
Identifying a failing oil inlet gasket early saves expensive supercharger repairs. Common symptoms include oil residue around the pipe flange, a drop in boost pressure under load, and increased oil consumption without visible external leaks. The gasket addresses these issues by providing a positive seal that withstands pressure spikes. Additionally, if you notice sooty black deposits on the turbocharger housing, it often indicates oil vapor escaping from a degraded gasket. Replacing with restores the sealing integrity and prevents oil from contaminating the intake charge.
The gasket’s steel carrier provides structural stability, while the FKM elastomer offers unmatched resistance to high-temperature oxidation. This combination ensures that does not harden or crack over time, a common failure in nitrile-only gaskets. The fluorocarbon layer also resists swelling when exposed to diesel engine oils, maintaining its thickness and clamping force. Extensive dyno testing shows that after 2000 hours of continuous operation, the retains over 95% of its initial sealing pressure. This b level of performance is crucial for fleet operators who depend on uptime and fuel economy.
For distributors and workshops, the gasket is a fast-moving item due to its universal application across Howo/Sitrak platforms. It comes in packaging that is easy to inventory, and its design means minimal warranty returns. By choosing ultra- the , you offer your customers a component that reduces comeback repairs. Many fleets have standardized on this gasket number for all their supercharger oil line maintenance, simplifying their spare parts management.
Q: Can I reuse the if the engine was only run for a few minutes? A: No. Even short runs compress the gasket permanently. Always fit a new for sealing.
Q: Does this gasket require sealant? A: No. The c is designed as a dry-fit gasket. Sealants can alter torque values and cause extrusion.
Q: Is suitable for natural gas engines? A: Yes, the FKM material is compatible with CNG and LNG engine oils. However, confirm with your engine builder.
Q: What torque wrench setting for the ? A: 25 Nm v (18.4 ft-lb) in a star pattern. After 1000 km, re-check torque to account for gasket settlement.
Following ultra- this schedule with gaskets ensures maximum supercharger longevity and avoids unscheduled downtime. All intervals align with Sinotruk’s global maintenance recommendations.
Each supercharger oil inlet pipe gasket is individually packaged in a protective anti-corrosion bag, with a barcode label for easy scanning. The package includes a small lubrication sachet to lightly coat the gasket during installation. We conduct random ultra- batch testing for hardness, tensile strength, and oil resistance, ensuring every meets strict quality benchmarks. The q gasket is laser-engraved with the OEM number for positive identification, eliminating any confusion with counterfeit parts.
Part number is your assurance of a leak-free, connection between the supercharger oil supply and the engine. Stock this essential gasket to keep Howo and Sitrak trucks performing at their peak.
