In the automotive industry, DYH Y-type seals and hydrogenated nitrile rubber (NBR) ,inflatable seal are two key reinforced inflation seals for car air pumps. Below is a detailed introduction to them:   DYH Y-type seals for car air pumps:   Material characteristics: Made of modified polytetrafluoroethylene (PTFE), with improved material properties through the addition of special fillers. The modified PTFE significantly enhances wear resistance, giving it self-lubricating properties in dry air environments. This material optimization allows the seal to maintain a low coefficient of friction while enhancing mechanical strength and dimensional stability.   Temperature adaptability: Exhibits wide temperature resistance, covering an operating temperature range of -100℃ to 260℃, adapting to the various climatic conditions of car air pump operation.   Pressure capacity: Maximum operating pressure up to 20MPa, meeting the seal inflatable requirements of car air pumps under high-pressure conditi…
