When sealing performance, temperature stability, and chemical resistance are essential, Klinger materials are among the most trusted in the industry. At Stephens Gaskets, we’re a leading Klinger washers supplier, manufacturing precision components from high-quality Klinger gasket materials for use in industrial, chemical, and mechanical applications.
This guide explains what Klinger washers are, why they’re so effective, and where they’re best applied. Whether you’re looking to buy Klinger washers for a one-off project or require ongoing supply for OEM production, this article will help you understand their value.
What Are Klinger Washers?
Klinger washers are sealing components made from Klinger gasket materials – a range of high-performance fibre-reinforced synthetic and composite sheets. These materials are engineered to provide robust sealing under demanding temperature, pressure, and chemical conditions.
Common Klinger materials include:
- C-4430: Ideal for steam, oils, water, and weak acids.
- C-4324: Designed for general industrial use with good chemical resistance.
- C-4400/C-4401: Multi-purpose materials for fluids, gases, and higher temperatures.
These washers are typically die-cut or machined from Klinger sheet products and are known for being industrial sealing washers capable of handling pressure and harsh media.
Benefits of Klinger Gasket Materials
1. Temperature Resistance
Klinger washers can withstand continuous temperatures of up to 250°C (and intermittent peaks above), making them ideal for steam and high-heat applications.
2. Chemical Resistance
Klinger materials resist a wide range of media including water, oils, fuels, steam, mild acids, and some aggressive solvents.
3. High Compressibility
Their layered fibre structure allows good conformability to flange faces, which creates a tight seal even on uneven or worn surfaces.
4. Pressure Handling
Designed for use in pressure vessels, pipe flanges, and mechanical joints, Klinger washers maintain sealing integrity under load.
Applications: Where Should You Use Klinger Washers?
