PTFE Tri Clover Gasket

Product Description

A PTFE Tri Clover Gasket (also known as a Tri-Clamp gasket) is a sanitary gasket designed for use in Tri-Clamp connections in piping systems. These gaskets are commonly used in industries such as food and beverage, pharmaceuticals, and bioprocessing due to their chemical resistance, durability, and ability to provide a secure, hygienic seal.

Components of a PTFE Tri Clover Gasket:

1. PTFE Material

• Composition:
  The gasket is primarily made of polytetrafluoroethylene (PTFE), either in its pure form or a modified variant.
• Properties:
  • Excellent chemical resistance to a wide range of substances.
  • Inert and non-reactive, ensuring compatibility with high-purity and sensitive applications.
  • High-temperature tolerance (typically -200C to +260C).
  • Non-stick, reducing the potential for product adhesion.

2. Optional Additives or Fillers

• Enhanced PTFE:
  Some gaskets include fillers like glass, carbon, or graphite to improve mechanical properties, such as wear resistance or dimensional stability, without compromising chemical resistance.

3. Design Features

• Tri Clover Compatibility:
  Designed to fit between flanges of Tri-Clamp connections, ensuring a leak-proof and hygienic seal.
• Uniform Thickness:
  Maintains consistent sealing pressure across the flange.
• Hygienic Design:
  Smooth, non-porous surface minimizes the risk of bacterial growth and contamination.

4. Compliance

• Often certified to meet industry standards, such as:
  • FDA (Food and Drug Administration) compliance for food-grade applications.
  • USP Class VI certification for pharmaceutical and bioprocessing use.
  • 3-A Sanitary Standards for hygienic processing.

Variants

• Solid PTFE Gaskets: Used where maximum chemical resistance is required.
• PTFE Bonded or Envelope Gaskets: Combine a PTFE sealing surface with a more compressible core material for improved flexibility and sealing performance.
