Rod seals – Piston seals

Rod seals and piston seals are types of sealing elements used in hydraulic and pneumatic systems. They are designed to prevent fluid leakage around the rod or piston that moves through the cylinder.

Rod seals are used on rods that move outside of the cylinder, while piston seals are used on pistons that move inside the cylinder. Both types of seals are typically made from materials such as rubber, thermoplastic polymers, and elastomers.

Rod seals and piston seals function by creating a sealing pressure between the surface of the rod or piston and the inner surface of the cylinder. They are designed to withstand high temperatures, high pressures, and frequent back-and-forth movements.

Rod seals and piston seals are available in a range of styles and sizes to meet the specific needs of each application. Styles of rod seals include O-rings, V-rings, U-cups, pressure seals, and hydraulic seals, while styles of piston seals include lip seals, quad-rings, and step seals.

It is important to choose the right type of rod seal or piston seal to ensure effective and reliable sealing in hydraulic and pneumatic systems. It is also important to follow the manufacturer’s instructions for installation and replacement of the seals to ensure optimal performance and extended system life.
