IVAR.IVPT.HNBR - GAS flat seal

The IVAR.IVPT.HNBR flat seal category includes sealing components designed for gas distribution systems. These flat gaskets are used in steel pipe connections to ensure airtight and leak-free joints in natural gas, biogas and propane gas applications. The seals are suitable for operating temperatures from -20°C to +70°C and are rated for maximum pressure PN 10 and operating pressure PN 5. They are commonly used in residential and industrial gas supply systems where reliable sealing is essential.

Available in multiple sizes, these flat seals are compatible with standard steel pipe connections and are manufactured from HNBR (hydrogenated nitrile butadiene rubber), a material known for its resistance to gases and temperature fluctuations. They are ideal for use in pressurised gas lines and require precise installation to maintain system integrity.

How to choose

• Select the correct size based on the pipe diameter (e.g., 18mm, 22mm, 28mm, 35mm, 42mm, 54mm) to ensure a proper fit.
• Ensure compatibility with steel pipe connections and press fittings used in the system.
• Verify that the operating conditions (pressure and temperature) fall within the PN 5 and -20°C to +70°C range.
• Confirm that the application involves natural gas, biogas or propane gas in the gas phase.

Frequently asked questions

Can these seals be used in biogas systems?
Yes, the IVAR.IVPT.HNBR flat seals are suitable for biogas applications as they are designed for gas-phase use and are compatible with the materials and conditions found in such systems.

What is the maximum operating pressure for these flat seals?
The maximum operating pressure is PN 5, while the maximum pressure rating is PN 10. This makes them suitable for low- to medium-pressure gas systems.
