Metal Wipers for Hydraulic Cylinders — Urethane & Rubber Rings

Choosing Between Urethane Wiper Rings or Rubber Wiper Seals

Two common types of wipers you'll encounter are urethane wiper rings and rubber wiper seals. Each has unique advantages depending on your application.

Urethane Wiper Rings

Urethane wipers are ideal for demanding industrial environments. Their high level of toughness allows them to handle extreme conditions such as high pressures and mechanical stress. Most importantly, they’re also resistant to chemicals, making them perfect for hydraulic systems.

For example, CRC Distribution offers options like the MCU-Style seals like the Urethane Wiper Ring, which boasts a robust metal casing for enhanced reliability. View more urethane wiper rings here.

Rubber Wiper Seals

Rubber wiper seals are perfect for less demanding operations or where flexibility is key. These wipers are highly effective for standard systems and offer great affordability without compromising reliability.

Material Considerations for Metal Wipers

The material you choose for your wipers will significantly impact their effectiveness.

• Urethane: Resistant to chemicals, wear, and high pressures, urethane is a dependable choice for heavy industrial use.
• Rubber: Lower cost and flexible, rubber wipers are better suited for less harsh environments.
• Buna-N or Nitrile: Known for their oil and heat resistance, these materials are versatile and reliable.

How to Select the Right Design

Several variables influence which metal wiper design is the best for your system. Consider the following when making a decision:

• System Requirements: Assess the operating pressure, temperature, and environmental conditions your systems will face.
• Size Compatibility: Metal wipers are available in a wide variety of sizes, from 10 mm to over 200 mm. Ensure you select wipers that fit your system’s dimensions.
• Durometer Ratings: Urethane wipers are available in multiple durometer ratings (such as 92A), which affect their flexibility and hardness.
