xShop Now Genuine Bentley Seal Ring Online – Part 07C145039
The Genuine Bentley Seal Ring 07C145039 is an OEM turbo to exhaust manifold sealing component designed specifically for Bentley W12 engines. This high-temperature Bentley turbo gasket creates a secure seal between the turbocharger and exhaust manifold, helping prevent exhaust gas leaks and maintaining correct pressure flow within the turbo system.
In high-performance engines such as Bentley’s W12, precise sealing is essential. Even a minor leak at the turbo connection can affect boost pressure, engine response, and overall efficiency. This OEM Bentley seal ring is manufactured to exact factory specifications, ensuring a direct replacement without modification or adjustment.
Because the turbo system operates under extreme heat and pressure, the material used in this seal ring is engineered for durability and thermal stability. It withstands repeated heat cycles and maintains structural integrity over long service intervals. Technicians commonly replace this turbo's manifold sealing ring during turbo removal, exhaust work, or engine servicing to avoid future leakage issues.
At Europeanautospares, we supply genuine Bentley spare parts that meet original engineering standards. This part is brand new and suitable for professional installation. For W12 engines equipped with twin turbos, one seal ring is required per turbo.
Whether you are servicing your Bentley locally or maintaining a performance vehicle abroad, this Bentley exhaust sealing component helps preserve factory performance and reliability.

Crewe Powertrain Division & High-Pressure Exhaust Gas Containment Notice
This professional-grade, high-performance hot-side turbocharger inlet sealing ring set, featuring an advanced multi-layered core and specialized precision-crush concentric landing bands, is engineered strictly for the high-pressure exhaust manifold-to-turbine housing connections of the 6.0-liter twin-turbocharged W12 engine lineage powering the first- and second-generation Bentley Continental and Flying Spur series. Positioned directly at the structural interface where raw, high-velocity exhaust gas channels exit the exhaust manifolds to drive the twin heavy-duty turbochargers, these critical gaskets isolate hyper-heated exhaust gas columns operating under extreme backpressures and thermal transients scaling up to **950°C to 1000°C**.
Critical Thermodynamic Stress and Forced-Induction Failure Warnings: Technicians, independent exotic engine builders, and master diagnostics specialists must realize that the complex packaging of the 6.0L W12 engine bay traps immense, unyielding thermal energy behind the cylinder heads. Because the twin-turbo network layout relies on absolute pre-turbine exhaust gas velocity to spin the compressor wheels cleanly and minimize lag, these compression rings are precision-calibrated to act as zero-clearance, high-durability gas containment boundaries.
Never reuse old, crushed, or heat-cycled manifold-to-turbo inlet rings during a turbo replacement, engine-out refresh, or exhaust manifold service overhaul. Sourcing a sub-tier aftermarket substitute or attempting to re-torque a spent factory ring will cause immediate metallurgical failure. Under full overboost mappings—especially on high-output Speed and 700HP Supersports platforms—pre-turbine backpressures increase significantly. A compromised or non-OEM ring will yield an immediate hot gas leak. This pressurized leak acts as a high-heat blowtorch, rapidly cutting through the adjacent aluminum engine block castings, melting nearby engine wire looms, destroying vacuum control lines, and causing severe pre-turbine pressure drop-outs. This drop in velocity induces massive turbo lag, a notable loss of top-end horsepower, and triggers absolute boost deviation errors (such as P0299 low boost fault strings) inside the digital engine management computing loops.
Special caution applies to second-generation models and Supersports packages: these late-run vehicles execute highly aggressive factory anti-lag maps and elevated wastegate pressures, multiplying the mechanical shear forces exerted against the exhaust mating flanges.
Engine-Out Extraction & Mechanical Alignment Best Practices: Sourcing replacement sealing rings at the exhaust manifold-to-turbocharger junction **cannot be achieved with the W12 engine block secured inside the vehicle chassis; replacement strictly mandates a full powertrain drop using a heavy-duty hydraulic engine lift cradle table**.
Once the W12 powertrain assembly is safely isolated outside the vehicle bay, back off the specialized high-tensile copper-plated or multi-hex exhaust flange locking nuts. Technicians must use a specialized mirror detailing scraper or an ultra-fine abrasive pad to thoroughly clean the recessed landing grooves inside the turbine housing inlets. Never use coarse steel wire wheels or aggressive die grinders, which will easily gouge the precision-machined steel sealing tracks, creating a permanent micro-gap leak path that no fresh gasket can seal.
Wipe the mating surfaces entirely free of carbon soot crust and scale deposits using fast-evaporating chemical cleaners. Slide the new sealing ring squarely parallel into its designated seating pocket. Always source brand-new factory-grade high-tensile exhaust stud hardware and torque all flange fasteners in a multi-stage crisscross sequence exactly to the factory workshop manual specification: 30 Nm. Under-torquing allows thermal contraction to loosen the joint under cold starts, while over-torquing will stretch the high-heat studs past their elastic limits, risking a sheared stud under track-load expansion cycles. Re-verify all heat shielding wraps, lock the engine back into the chassis subframe, prime all oil and coolant lines, and execute an exhaustive tailpipe exhaust gas adaptation sweep via master diagnostics before field deployment.
Advanced Multilayer Inconel Steel Alloy Matrix Core
The primary sealing ring body is constructed from an advanced, multi-layered Inconel nickel-chromium-based superalloy matrix core. This specialized aerospace-grade metallurgy delivers exceptional yield strength, retains permanent elastic tensioning, and resists structural oxidation or material scaling under continuous exhaust gas stress cycles scaling past $+950^{\circ}\text{C}$.
Precision-Crush Concentric Landing Ring Profiles
The structural faces of the sealing ring integrate precision-formed concentric crush ridges designed to deform micro-elastically during initial flange torque-down. This technical configuration fills microscopic surface imperfections on the cast-iron manifold and steel turbine inlets, ensuring an absolute gas-tight seal against high-velocity exhaust backpressures.
