ePTFE (Teflon) Gaskets

gaskets

Expanded PTFE (ePTFE) gaskets provide extreme sealing capabilities for a wide range of applications. These gaskets are highly resistant to chemicals and high temperatures, and offer excellent performance in both high and low-pressure environments.

Our ePTFE gaskets are available in various forms, including gasket tape, sheet gaskets, and joint sealants. Their flexibility, long service life, and ease of installation make them a valuable solution for applications that require minimal maintenance and reliable sealing over time.

Features & Benefits

Easy to Cut

ePTFE gaskets are flexible and can easily be cut to a required shape and size, making them ideal for custom applications.
High-Temperature Resistance

Capable of withstanding temperatures up to 650°F.
Low Bolt-Load Sealing

Provides effective sealing with low bolt load, reducing stress on fragile flanges and piping.
Long Service Life

ePTFE gaskets offer exceptional durability, ensuring reliable sealing over long periods, even in demanding environments.

Design Specifics

Manufactured from expanded PTFE material, these gaskets are engineered to be chemically resistant, thermally stable, and flexible enough to form a reliable seal in various applications. The material’s ability to resist creep and cold flow ensures that the gasket maintains its integrity over time, even in environments where the bolt load is low or subject to vibration.

How ePTFE Gaskets Work

The gasket material provides a tight, secure seal without the risk of damage to the sealing surface, making it ideal for systems requiring both durability and flexibility. These unique properties make ePTFE gaskets an excellent choice for sealing delicate or fragile components like pipe flanges.
