Product Description

A1 Type Dust Wiper Seal For Hydraulic Cylinder

A1 is a single acting dust seal ensuring that foreign particles do not penetrate into the hydraulic systems, advoiding wear and damage to all the internal components including seals. A1 dust seal is to prevent dust, dirt, sand or fines from entering. In addition, A1 dust seal installation does not require ring screws or brackets. No strict tolerances and metal inserts in the requirement.



- Very good wiping performance;

- Not twisting in the housing;

- Specially design to prevent big particles to go into the system;

- Wide range of dimensions;

- Used in heavy conditions by the good mechanical properties of PU material;

- Secure seating into groove;

- Good wear resistance;

- High temperature resistance;

- Excellent media resistance.

A1 Type Dust Wiper Seal For Hydraulic Cylinder 0


The Role Of The Seal:

Wiper seal: It is designed to prevent external contaminants from coming inside the assembly of the cylinder.

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 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.

(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.

Buffer seal: The rod seal is protected against fluid pressure peaks that can lead to fluctuating the system pressure with the help of buffer seals.
