What Are Felt Washers?

Felt washers are thin, circular, or ring-shaped components made from compressed or matted felt material. This material is typically derived from natural fibres, such as wool or synthetic fibres like polyester and nylon. Felt washers are known for their unique properties, including high absorbency, durability, and resistance to wear and tear.

Common Uses of Felt Washers

Felt washers find applications in a wide range of industries, thanks to their versatile characteristics. Here are some common uses:

  • Sealing– Felt washers are excellent at creating a seal between two surfaces. They can prevent the leakage of liquids or gases, making them invaluable in plumbing, automotive, and industrial sealing applications.
  • Vibration Dampening– Due to their soft and cushioning nature, felt washers are used to absorb vibrations and reduce noise in machinery and equipment.
  • Friction Reduction– Felt washers can reduce friction between moving parts, enhancing the longevity and efficiency of mechanical systems.
  • Protection– They are often used to protect delicate surfaces from scratches or damage in applications like woodworking and metalworking.
  • Insulation– In electrical applications, felt washers provide electrical insulation and prevent contact between conductive components.

Factors Affecting Felt Washer Lifespan

The longevity of felt washers can be influenced by a variety of factors, each of which deserves careful consideration. By understanding these factors, you can take proactive steps to ensure your felt washers have an extended and reliable lifespan.

A. Environmental Factors

  • Temperature– Extreme temperatures can make felt washers brittle (hot) or stiff (cold).
  • Humidity– Excess moisture can lead to mold, while dry conditions affect flexibility.
  • UV Exposure– Prolonged sunlight exposure degrades felt material.

B. Mechanical Factors

  • Pressure– Excessive pressure can flatten or deform felt washers.
  • Friction– High friction wears down felt material.
  • Impact and Vibration– Continuous impact or vibrations may cause deterioration.
