Frequently Asked Questions

What is a kammprofile / serrated gasket?

A kammprofile gasket consists of a serrated metal core with a soft facing material (graphite or PTFE) bonded to each side. It combines the strength of metal with the conformability of soft materials.

What materials are available for the metal core?

We offer stainless steel (304, 316, 316L), carbon steel, Inconel, Monel, Hastelloy, and other alloys depending on your application requirements.

What facing materials do you use?

We offer flexible graphite (high temperature, up to 650°C), PTFE (chemical resistance, up to 260°C), and non-asbestos materials for various service conditions.

What are the standard lead times?

Stocked sizes ship within 24–48 hours. Custom production takes 7–15 working days. For complex custom designs, allow 15–20 working days.
