Guilcam 20PCS M8 Exhaust Manifold Hex Nuts, OEM #A1201420072

Guilcam 20PCS M8 Exhaust Manifold Hex Nuts, OEM #A1201420072

• High Quality Material: This product is manufactured from a copper alloy. The material offers excellent ductility and toughness, as well as good compressive strength, enabling it to withstand a certain degree of external impact without deformation or fracture. Copper alloys possess superior thermal conductivity, allowing them to rapidly dissipate heat generated by the exhaust system and maintain structural integrity.
• Wide Application: This product features an M8×1.25 thread, matching the standard thread specifications commonly used in automotive exhaust systems. It can directly replace OEM part #A1201420072 without the need for additional modifications or adapters. Measuring 0.69×0.69×0.37 inches, its compact size makes it suitable for a wide range of car and lorry exhaust systems.
• Easy Installation: Before installation, clean the surface of the bolt at the exhaust system connection point. Then align the nut with the bolt threads and gently screw it in by hand to ensure the threads are fully engaged. Next, use a spanner to tighten it slowly, applying the correct amount of force to avoid over-tightening or under-tightening. Once tightened, check that the nut is flush against the mating surface.
• Sealing Function: The sealing function of this product ensures a tight fit between the nut and bolt, effectively filling gaps at the exhaust system connection points to prevent exhaust leaks and ensure the system operates normally. The product prevents issues such as exhaust gas leakage and increased noise caused by poor sealing, whilst reducing wear on exhaust system components and extending the system's service life.
• Portability: This product is lightweight, making it easy to carry and store. Motorists can keep it in their vehicle tool kit to address issues such as loose or damaged exhaust system nuts at any time and in any location. Furthermore, the product has a simple design that is resistant to damage and requires no special maintenance during storage, making it highly convenient whether used for routine maintenance or as an emergency solution during long journeys.
