Kammprofile Gasket (Basic Style)

At Kriloha Ltd., we understand that in high-pressure engineering, the simplest designs are often the most effective. For flanges that provide their own centering—such as Tongue and Groove or Male and Female joints—the Kriloha Kammprofile Gasket (Basic Style) offers the ultimate in mechanical sealing efficiency. As a top supplier of industrial seals and gaskets, Kriloha Gaskets has engineered the Basic Style to provide a “fortress-level” seal in the most compact footprint possible.

The “Basic Style” consists strictly of the serrated sealing core and its composite facings. By eliminating the outer centering ring, we provide a gasket that can be precisely seated into recessed grooves. The core is precision-machined from high-quality 316L Stainless Steel (or exotic alloys like Monel and Inconel) with concentric V-grooves. These grooves are then faced with high-purity flexible graphite. When the flange is torqued, the graphite is compressed into the grooves and against the flange face simultaneously, creating multiple redundant sealing rings that act as independent barriers to the process media.

Manufacturing the Kriloha Basic Style requires absolute dimensional accuracy. Since these gaskets often sit in tight-tolerance grooves, we ensure the Outer Diameter (OD) and Inner Diameter (ID) are machined to exacting standards to prevent binding or “bunching” during installation. By choosing Kriloha Ltd., you are investing in a product that combines the “flow” of mineral sealants with the “force” of precision-machined steel. It is the definitive heavy-duty solution for maintenance teams working with specialized flange geometries that demand the highest levels of safety and longevity.

Primary Use Cases

Confined Tongue and Groove Flanges: The Basic Style (without an outer ring) is specifically designed to fit into recessed flange grooves where a centering ring is not required.
Heat Exchanger Pass-Partition Bars: Ideal for complex internal heat exchanger geometries where space is limited and multiple sealing paths are needed.
Male and Female (Spigot) Joints: Providing a robust, high-pressure seal for specialized industrial piping connections.
Valve Bonnets and Sight Glasses: Used in high-temperature applications where a thin, high-strength profile is necessary for a secure fit.
High-Temperature Reactors: Reliable containment for volatile chemicals and superheated gases in synthesis loops.

FAQs

When should I use the Basic Style instead of a version with a centering ring?

The Basic Style is used exclusively for flanges that have a built-in centering mechanism, such as Tongue and Groove or Male and Female (Spigot) joints. If you are using standard flat-face or raised-face flanges, you should use a version with an outer ring.

Can the Basic Style handle high-velocity media?

Yes. Because the soft facing is mechanically locked into the serrations of the solid metal core, it is highly resistant to “washing out” or erosion, even in high-velocity steam or gas lines.

What is the standard thickness for a Kriloha Kammprofile?

The standard metallic core thickness is 3.0mm or 4.0mm, with 0.5mm of facing material on each side, resulting in a total nominal thickness of 4.0mm or 5.0mm.

Are these gaskets reusable?

If the metallic core remains undamaged and hasn’t been over-compressed, it can often be cleaned and re-faced with new graphite or PTFE, making it a sustainable and cost-effective choice for large-scale equipment.

How do I prevent the gasket from falling out during vertical installation?

Because the Basic Style is designed for confined grooves, it typically “seats” into the groove. For difficult installations, a very small amount of aerosol adhesive can be used on the flange face to hold the gasket in place until the joint is closed.
