PTFE gaskets

Alpi Guarnizioni PTFE gaskets are sealing solutions widely used in industry thanks to the excellent properties of PTFE (polytetrafluoroethylene). This technical plastic material is valued for its chemical inertness, thermal stability and low friction coefficient, characteristics that make it ideal for sealing applications in complex operating conditions.

Alpi Guarnizioni uses PTFE to manufacture gaskets for both static seals and systems subject to mechanical stress, ensuring reliability, safety and long life.

Advantages of PTFE gaskets

Alpi Guarnizioni PTFE gaskets offer numerous advantages over other sealing materials, particularly in the presence of aggressive fluids or variable operating conditions.

The main benefits include:

• Very high chemical resistance, compatible with most industrial fluids
• Wide operating temperature range
• Low friction coefficient, which reduces wear and seizure
• Excellent dimensional stability, even over the long term
• No ageing or hardening, typical of some elastomers

These characteristics make PTFE seals a reliable choice for systems that require continuous operation and reduced maintenance.

Applications of PTFE gaskets

Thanks to their versatility, Alpi Guarnizioni PTFE gaskets are used in numerous industrial sectors.

They are commonly used in:

• Chemical and petrochemical industry
• Process plants and industrial piping
• Valves, pumps and flanges
• Energy and plant engineering sector
• Applications with corrosive or aggressive fluids

PTFE gaskets are particularly suitable when high reliability, chemical compatibility and consistent performance are required, even under critical operating conditions.

Customisation of PTFE gaskets

Every application has specific requirements. That is why Alpi Guarnizioni offers customised PTFE gaskets, tailor-made to suit actual operating conditions.

Customised solutions include:

• Manufacture of parts in PTFE and filled materials
• Selection of the most suitable material (PTFE, carbographite, PEEK®)
• Customised dimensions, thicknesses and geometries
• Dedicated technical support during the production phase

Customisation improves sealing efficiency and extends the operational life of components.
