Pneumatic cylinder seal kits are key components in the pneumatic cylinder sealing system. They are typically installed near the piston or piston rod to prevent compressed air leakage and maintain stable internal cylinder pressure.

Among various sealing materials, nitrile rubber (NBR) is one of the most common and widely used materials in pneumatic cylinder seal kits. NBR is widely used in pneumatic systems due to its good oil resistance, wear resistance, and moderate elasticity.

PTFE materials have excellent heat resistance, and some high-performance pneumatic cylinder seal kits can operate stably in environments approaching 200℃. Therefore, overall, the heat resistance temperature of high-performance pneumatic cylinder seal kits can reach approximately 200℃.
