How does a double lip rubber TC seal work?

The double lip design allows for better sealing performance compared to single lip seals. Here's how it works:

  1. The primary lip acts as the first line of defense, preventing fluid leakage.
  2. The secondary lip provides an additional layer of protection against dust, dirt, and other contaminants.
  3. This design reduces wear and tear on the seal, leading to a longer lifespan.

What materials are used in double lip rubber TC seals?

Double lip rubber TC seals are typically made from various rubber compounds, including:

  1. Nitrile Rubber (NBR): Known for its oil resistance, making it suitable for petroleum-based fluids.
  2. Fluorocarbon Rubber (FKM): Offers excellent chemical resistance, ideal for harsh environments.
  3. Polyurethane: Provides a strong resistance to abrasion and is used in demanding applications.
