PTFE Gaskets for Chemical Processing, Food Processing & Industrial Applications
M&P Sealing manufactures and supplies high-performance PTFE gaskets for demanding industrial sealing applications. PTFE (Polytetrafluoroethylene), commonly known as Teflon®, offers exceptional chemical resistance, low friction properties, and excellent performance across a wide temperature range.
PTFE gaskets are widely used in chemical processing, food and beverage manufacturing, pharmaceuticals, water treatment, pulp and paper, and other industries where corrosion resistance and product purity are critical. M&P can provide standard flange gaskets, custom-cut PTFE gaskets, and precision-machined PTFE sealing components to meet your exact specifications.

Why Choose PTFE Gaskets?
PTFE is one of the most versatile gasket materials available for industrial sealing applications. Unlike rubber gasket materials that can degrade when exposed to aggressive chemicals, PTFE remains stable in contact with acids, solvents, caustics, and many corrosive fluids.
Its non-reactive properties make PTFE an excellent choice for applications where contamination cannot be tolerated. Food processing facilities, pharmaceutical manufacturers, and chemical plants frequently utilize PTFE gaskets to ensure leak-free sealing while maintaining product purity. PTFE is one of many materials available for our Industrial Gaskets and can be manufactured to meet a wide variety of sealing requirements.

PTFE vs. Rubber Gaskets
While rubber gaskets provide flexibility and a lower initial cost, PTFE gaskets offer superior performance in demanding industrial environments. PTFE is highly resistant to a wide range of chemicals, including acids, solvents, and caustic materials that can cause many rubber compounds to swell, degrade, or fail over time.
PTFE also maintains its sealing properties across a broader temperature range, making it an excellent choice for applications involving extreme heat, aggressive process media, or stringent cleanliness requirements. Unlike many elastomer materials, PTFE is non-reactive, non-contaminating, and available in FDA-compliant grades for food, beverage, and pharmaceutical applications.
For operations where reliability, chemical compatibility, and long service life are critical, PTFE gaskets are often the preferred sealing solution despite their higher upfront cost. The extended lifespan and reduced maintenance requirements can result in lower overall operating costs and improved equipment reliability. For extreme chemical and temperature applications, customers may also consider Kalrez® FFKM seals.
