Heavy-Duty Scraper Seals for Harsh Environments
Scraper seals are engineered to provide aggressive contamination control for hydraulic systems operating in the most severe conditions. Their primary function is to remove heavy and stubborn contaminants—such as caked-on mud, ice, weld spatter, and other industrial debris—from a cylinder rod before it retracts. This robust action prevents the severe contamination that leads to premature system failure in demanding environments.
Performance Sealing Inc. manufactures heavy-duty scraper seals designed to withstand extreme physical challenges where standard wiper seals, often called excluder seals, are insufficient.
Metallic Scraper Seals for Extreme Applications
Our scraper seals are built with metal components to deliver maximum durability and an effective, aggressive scraping action. These seals are the ideal solution for protecting heavy-duty equipment in industries like oil & gas, steel mills, and mobile construction.
- Duru-Scraper: This model features a metal spring energizer and a rubber-free design, making it immune to degradation in environments with aggressive chemicals, oils, or high temperatures. It is a preferred solution for aircraft braking systems and oilfield equipment.
- Bronze-Scraper: For the harshest conditions, this heavy-duty bronze scraper offers unmatched toughness. As a press-in component, it effectively removes hardened mud and solid ice, ensuring cylinder protection for equipment like snow plows and steel mill machinery.
Key Features of Our Scraper Seals:
- Engineered for extreme sealing applications involving mud, ice, and heavy debris.
- Features metallic components (bronze body or metal energizer) for maximum toughness.
- Excels in aggressive chemical and high-temperature environments.
Excluder seals are available in many different Duron® materials that are specified based on your conditions and parameters. For a complete proposal, submit a request for quote and we will respond, immediately.

Frequently Asked Questions (FAQ)
What is the difference between a scraper seal and an excluder seal?
While both prevent contamination, a scraper seal is designed for more aggressive action. Scrapers often use metallic components to remove heavy, adhered debris like mud and ice. Excluder seals (or wipers) are typically polymer-based and are designed to remove finer particles like dust and moisture.
Why is the Duru-Scraper rubber-free?
The Duru-Scraper is completely rubber-free to ensure reliable performance in environments where traditional elastomeric seals would quickly fail. This design makes it compatible with the aggressive chemicals, high temperatures, and demanding conditions found in the oil and gas, aerospace, and industrial sectors.
When should I choose the Bronze-Scraper?
The Bronze-Scraper is necessary when your equipment operates in environments with severe, impactful, or frozen contaminants. If you need to mechanically break away and remove hardened mud, ice, or other solid debris from a rod, the heavy-duty design of a solid metal scraper is the most effective and reliable solution.
