PTFE envelope gaskets offer a versatile range of size options to accommodate various industrial and mechanical applications. They are available in both standard nominal sizes (DN15 to DN2000) and non-standard dimensions, starting from as small as 12mm. The envelope thickness typically comes in 0.5mm or can be customized as required. Additionally, these gaskets are offered in milled or slit forms, providing flexibility for different installation and performance needs.
Key Points Explained:
-
Standard Nominal Sizes (DN Series)
PTFE envelope gaskets are manufactured in a comprehensive range of standard nominal sizes, denoted by DN (Diameter Nominal) values. These include:- DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300, DN350, DN400, DN450, DN500, DN600, DN700, DN800, DN900, DN1000, DN1200, DN1400, DN1600, DN1800, and DN2000.
This wide range ensures compatibility with most piping and flange systems across industries.

-
Non-Standard Dimensions
For specialized applications, ptfe gasket can be produced in non-standard sizes. The smallest available size starts at 12mm, making them suitable for precision equipment or tight spaces. Custom dimensions can be negotiated with manufacturers to meet unique project requirements. -
Envelope Thickness Options
- Standard thickness: 0.5mm, which balances durability and flexibility.
- Custom thickness: Available upon request to address specific pressure, temperature, or sealing needs.
Thickness variations impact the gasket's compression and sealing efficiency, so selecting the right option is critical for performance.
-
Milled vs. Slit Forms
- Milled gaskets: Precision-cut for consistent dimensions, ideal for high-pressure or high-temperature applications where exact tolerances are crucial.
-
Slit gaskets: Cost-effective and suitable for less demanding environments, though they may require additional trimming during installation.
The choice between milled and slit forms depends on budget, application rigor, and installation preferences.
-
Customization and Flexibility
Manufacturers often provide tailored solutions, including bespoke sizes, thicknesses, and forms. This adaptability makes PTFE envelope gaskets a reliable choice for both standard industrial use and niche applications.
Have you considered how the operating environment (e.g., chemical exposure or thermal cycling) might influence your choice of gasket size or thickness? These quiet yet critical components often determine the longevity and safety of entire systems.
