Product Description
The genuine Nissan part number 15056-7T801 O-ring seal (SEAL-O RING) is a precision-engineered sealing component designed to provide a leak-free seal at critical points on internal combustion diesel engines, specifically Nissan TD and QD engine series. The function of this O-ring is to prevent the leakage of fluids (engine oil, coolant, or fuel) between mating surfaces, pipe connections, or pump assemblies, even under substantial pressure and operating temperature fluctuations.
Technical Features and Function
The sealing ring is manufactured from a specialized, oil- and heat-resistant elastomer (such as NBR or FKM) that resists aggressive chemicals and mechanical deformation. Ageing, cracking, or flattening of the seal can lead to fluid leaks, pressure loss, and contamination of surrounding components; therefore, replacement according to OEM specifications is essential during servicing or overhaul.
