The Role Of TheSeal:
- Rod seal: Acts a pressure barrier and helps the operational fluid inside of the cylinder to regulate the fluid film extending with the connecting rod’s surface. This is essential in inhibiting the corrosion of the rod and the lubriC.A.Tion of the wiper seal.
- Piston seal: Acts as a barrier to the pressure and prevents the fluid from passing the piston. Necessary for maintaining the position when at rest or for the cylinder’s dominant motion.
- (Rod and piston) functions: Prevents contact of metal-to-metal between parts, leading to keeping the piston and connecting rod accurately centered within the assembly of the cylinder. Helps in improving performance of the piston and rod waterproofing system.
