Metric Wiper Seals

A wiper seal is a protective sealing component fitted to hydraulic and pneumatic cylinders to clean the reciprocating rod during operation. Also known as scraper seals, hydraulic wiper seals remove dirt, moisture and debris from the rod surface before contaminants can enter the cylinder system. This helps protect internal hydraulic seals, reduce wear and extend equipment lifespan. Rubber wiper seals are manufactured from durable materials that provide flexibility, abrasion resistance and reliable sealing performance in demanding environments. Metric wiper seals are produced to metric dimensions for compatibility with a wide range of hydraulic cylinder applications.

There are several types of wiper seals available depending on operating conditions and application requirements. Common options include press-fit scraper seals, snap-in hydraulic wiper seals and double-lip designs for enhanced contamination protection. Swan Seals supplies metric wiper seals manufactured from durable polyurethane materials that offer excellent wear resistance and long service life in hydraulic systems. Different scraper seal profiles are available to suit varying rod speeds, environmental conditions and cylinder configurations, ensuring effective rod cleaning and reliable sealing performance across industrial applications.

Hydraulic wiper seals are widely used across construction, manufacturing, agriculture, material handling and heavy engineering industries where hydraulic cylinders operate in contaminated environments. Wiper seals are commonly fitted to excavators, agricultural machinery, lifting equipment, presses and industrial automation systems to prevent dirt and debris from damaging internal cylinder components. Rubber wiper seals help maintain hydraulic system efficiency, reduce maintenance requirements and extend the lifespan of seals and cylinders by minimising contamination ingress. Their protective function makes metric wiper seals essential for reliable hydraulic cylinder performance in demanding operating conditions.

Choosing the correct wiper seal depends on factors including rod size, operating environment, contamination levels, speed and temperature conditions. Selecting the right hydraulic wiper seal profile and material is essential for achieving effective rod cleaning and long-lasting performance. Polyurethane rubber wiper seals are commonly used in hydraulic systems due to their excellent abrasion resistance and durability under demanding operating conditions. It is also important to ensure compatibility with the hydraulic cylinder design and existing sealing system to maximise protection and sealing efficiency. Swan Seals offers a comprehensive range of metric wiper seals and scraper seals suitable for industrial and hydraulic applications.
