PTFE O-Rings

Advantages of PTFE O-Rings

Following are some of the benefits of using the O-rings made from PTFE

• The operating temperature range is -300 oF to 500 oF.
• These O-rings are provided in white color.
• The O-rings are phthalate free and X-ray detectable.
• These O-rings gain their physical properties from the PTFE material. They are as summarized below:
• Excellent Abrasion Resistance
• Good Compression Set Resistance
• Good Elongation Resistance
• Excellent Flame Resistance
• Fair Low Temperature Flexibility
• Good Tensile Strength
• Excellent Tear Resistance
• Low Friction
• Excellent Moisture Resistance
• Good Cryogenic Capabilities
• PTFE is a chemically inert material. Its chemical resistance properties can be summarized as below:
• Excellent resistance against brake fluids, hydraulic fluids, ketones, ozone, petroleum oils, silicone fluids, transmission fluids, and water.
• Good resistance against dilute acids, dilute alkalis, steam, and strong acids.
• Due to low friction characteristics, PTFE O-rings meet USDA, FDA, and 3-A dairy requirements. Hence, these O-rings are perfect for several food and beverage processing applications.

Restrictions

You need to keep in mind that PTFE O-rings are not compatible with:

• High vacuum seals
• High temperature steam
• Low compression vacuum sealing flanges
