AFLAS (TFE/P) O-Rings

AFLAS® (TFE/P) O-Rings Material Description:

AFLAS® is a registered trademark of Asahi Glass Co., Ltd. Properly formulated and cured AFLAS® products deliver outstanding results in many operating environments. Results using AFLAS® fluoropolymers may vary depending upon the fabricator's formulation, manufacturing process, and proper application to the operating environment.

AFLAS® has excellent resistance to ozone and weathering along with a wide range of chemicals, including acid, base, and steam. A reliable choice for applications that work in tough environments. Disadvantages include high compression set and extrusion resistance especially at high temperatures.

Engineered Seal Products has the expertise and inventory for your AFLAS® (TFE/P) o-ring applications. For over 50 years, ESP has been the leading engineering, quality, and supply chain choice for both standard and custom sealing applications. A seal, no matter the application, has to do just that.

AFLAS® (TFE/P) Advantages:
  • Excellent heat resistance
  • Chemical resistance including resistance to strong acids and bases
  • High electrical resistivity
  • Excellent oil resistance.
AFLAS® (TFE/P) Disadvantages:
  • High compression set
  • Low extrusion resistance especially at high temperatures
  • Poor cold temperature resistance

Temperature ranges will apply to the majority of media for which the material is potentially recommended. With some media however, the service temperature range may be significantly different. ALWAYS TEST UNDER ACUTAL SERVICE CONDITIONS.

ESP’s shelf life recommendation is based on the AS5316 standard and intended to be utilized by those organizations who do not already have specific recommendations for the control of elastomeric seals. It should be noted that the packaging of the elastomeric seals prior to assembly into a product is an integral part of the controlled storage procedure. It provides a positive means of product identity from the time of manufacture to the time of assembly.
