Kammprofile Gaskets

Kammprofile gaskets are engineered for applications requiring superior sealing performance, low emissions, and reliable operation under demanding conditions. Featuring a serrated metal core with soft sealing layers bonded to each side, Kammprofile gaskets combine the strength of a metallic gasket with the sealing effectiveness of a soft gasket material.

Widely used in refineries, chemical plants, power generation facilities, and industrial processing operations, Kammprofile gaskets provide exceptional sealing integrity while helping reduce fugitive emissions and product loss.

At M&P Sealing, we supply high-quality Kammprofile gaskets manufactured to meet the performance requirements of critical industrial applications.

What Is a Kammprofile Gasket?

A Kammprofile gasket consists of a precision-machined metal core featuring concentric serrations on both sealing faces. Soft sealing materials such as graphite, PTFE, or other facing materials are applied to the serrated surfaces. When compressed between flanges, the serrated metal core concentrates sealing stress while the facing material conforms to flange imperfections, creating a highly effective seal. Kammprofile gaskets are often selected as an upgrade from conventional sheet gaskets and are commonly used as an alternative to spiral wound gaskets in certain applications.

Kammprofile Gasket Construction

A typical Kammprofile gasket consists of:

• Serrated metal core
• Soft sealing layer on both sides
• Optional guide ring for easier installation and centering

The combination of metallic strength and soft sealing materials provides reliable performance across a wide range of industrial applications.

Kammprofile vs. Spiral Wound Gaskets: What’s the Difference?

Both Kammprofile and spiral wound gaskets are widely used in critical industrial sealing applications, but each offers unique advantages depending on operating conditions, flange condition, and sealing requirements.

Kammprofile Gaskets

Kammprofile gaskets feature a solid metal core with precision-machined serrations and soft sealing layers applied to each side. This design creates high sealing stress while maintaining excellent blowout resistance and low-emission performance.

Advantages of Kammprofile Gaskets:

• Excellent sealing performance at lower bolt loads
• Ideal for damaged or uneven flange surfaces
• Reduced fugitive emissions
• Greater resistance to handling damage
• Often preferred for heat exchanger applications
• Easier installation and removal in certain applications

Spiral Wound Gaskets

Spiral wound gaskets consist of alternating layers of metal winding and soft filler material, typically with an outer guide ring. They are designed to provide flexibility and resilience under varying temperatures and pressures.

Advantages of Spiral Wound Gaskets:

• Excellent recovery from thermal cycling
• Performs well under fluctuating pressure conditions
• Suitable for a wide range of temperatures and pressures
• Commonly specified for piping systems and standard flange connections
• Available in numerous material combinations

Which Gasket Is Right for Your Application?

The best gasket choice depends on several factors, including operating pressure, temperature, flange condition, bolt load availability, and emissions requirements. Kammprofile gaskets are often selected when maximum sealing performance, low emissions, and flange surface imperfections are concerns. Spiral wound gaskets are frequently chosen for general industrial service where flexibility and recovery characteristics are important.
