NBR rubber seal is a seal made of NBR (nitrile butadiene rubber) material. NBR is a synthetic rubber with good oil resistance, abrasion resistance and heat resistance. It is also widely used in the field of seal manufacturing.
NBR rubber seals are commonly used in industrial equipment, automobiles, machinery and hydraulic systems to prevent the leakage of liquids, gases and dust. Its main function is to form a seal between two or more components to ensure the normal operation of the system and prevent unnecessary leakage and losses.
The upper timing chain cover gasket is a crucial component in engines, acting as a seal between the engine’s upper timing chain cover and engine body to prevent lubricant leaks. Its flexible rubber construction guarantees accurate installation and effective sealing. It is necessary to keep the engine oil system’s optimal lubrication and engine efficiency. The gasket possesses certifications from REACH, ASTM D2000, SAE J200, ISO/TS 16949, and ISO 9001. Maintaining sealing, preventing chain loosening, reducing noise and vibration, and improving engine performance are its key goals. Because the gasket is composed of rubber and components that are resistant to oil, it will continue to seal even in the smallest engine part flaws.

Las juntas para tubos de bujías son componentes de estanqueidad esenciales en los motores, ya que dirigen la bujía hacia la cámara de combustión y garantizan su estanqueidad frente a la presión. Están fabricadas con materiales flexibles, como silicona o caucho, y evitan que se escapen la presión y los productos de la combustión. También mantienen el entorno de funcionamiento típico de la bujía, impidiendo la entrada de contaminantes e impurezas. Una junta desgastada o vieja puede afectar negativamente al rendimiento del motor, provocando fallos de encendido, una concentración desigual de la mezcla y una menor eficiencia del combustible. Las juntas son resistentes a las altas temperaturas, a los productos químicos y al desgaste. Las normas de certificación incluyen ISO 9001, ASTM D2000, SAE J200, AMS-Rubber y los requisitos de los fabricantes de equipos originales. Estas normas ayudan a garantizar la calidad de las juntas y su rendimiento en diversas industrias. Las revisiones y sustituciones periódicas son cruciales para mantener el correcto funcionamiento del motor.
