Wipers & Scrapers
Help keep dirt, moisture, and contaminants out of hydraulic and pneumatic systems
Wipers and scrapers are rod-side sealing elements that remove dirt, moisture, and debris to prevent contamination from entering hydraulic and pneumatic systems.
They protect critical components, support seal performance, and help reduce wear and premature failure.
What Are Wipers and Scrapers?
Wipers and scrapers are sealing elements installed on the rod side of hydraulic and pneumatic cylinders to remove contaminants during rod movement. As the rod retracts, they wipe away dirt, dust, moisture, and debris to help prevent those materials from entering the system.
Their primary role is to protect internal components—including rod seals, cylinder walls, and hardware—from external contamination. By maintaining a cleaner operating environment inside the system, wipers and scrapers help support consistent performance and reduce the risk of premature wear.
Key Takeaways
- Designed to exclude dirt, dust, moisture, and other contaminants
- Help protect rods, cylinder walls, rod seals, and other critical components
- Available in snap-in, press-fit, double-lip, and PTFE-based styles
- Some profiles also support secondary sealing or film-breaking performance
- Profile selection depends on pressure, speed, space, environment, and sealing system design
Materials
Wipers and scrapers are available in a range of materials selected based on application conditions such as temperature, speed, media, and wear requirements.
Common material options include:
- Polyurethane materials
- Rubber compounds
- PTFE-based designs
- Engineered materials for demanding environments
Common Applications
Wipers and scrapers are used across hydraulic and pneumatic systems where contamination control is critical—especially in demanding environments where equipment is exposed to dirt, moisture, and debris.
Common applications include:
- Oil & gas equipment
- Hydraulic cylinders in drilling and completion operations
- Frac pumps and pressure control equipment
- Mobile and heavy-duty equipment
- Industrial fluid power systems
- Equipment operating in outdoor or contaminated environments
