Key Features

  • Made of polytetrafluoroethylene (PTFE) for use with a variety of chemicals, fluids, and gases
  • Round in shape to provide a seal between cylindrical overlapping surfaces
  • Can be used across a wide temperature range from -328 degrees F (-200 degrees C) to 500 degrees F (260 degrees C)
  • Durometer (hardness) of 55D for resistance to penetration
  • Meets standards defined by Aerospace Standard AS568A

Product Description

This PTFE O-ring is white in color, has a durometer of 55D, a round cross-section, and is designed for use in a wide variety of sealing applications.

PTFE has excellent heat, fuel, and chemical resistance and is acceptable for temperature applications between -328 degrees F (-200 degrees C) to 500 degrees F (260 degrees C). It can be used outdoors, with lubricants, hydrocarbons, acids, alkalis, detergents, alcohol, ketones, steam and refrigerants, and also has good electrical resistance. PTFE is vulnerable to high vacuum seals, low compression vacuum sealing flanges, and super-heated steam.

This PTFE O-ring has a shore durometer of 55D. Shore durometer is the hardness of a material, and its resistance to permanent indentation. A higher durometer value indicates greater resistance to indentation on a scale of 0 to 100, with 100 indicating no indentation.

O-rings commonly provide a pressure and fluid seal between cylindrically shaped, overlapping mating surfaces and are commonly seen in engines, faucets, flanges, valves and various cylinders. They are circular in shape, with a round cross section and a hole in the center, similar to a doughnut. O-rings are available in various sizes, and can be ordered based on required nominal inside diameter (ID), outer diameter (OD), and cross-sectional (CS) diameter.

This PTFE O-ring meets standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings.
