Kaxite Sealing is an ISO 9001 certified Kammprofile gaskets manufacturer and wholesale supplier in China. For over 10 years, we have engineered high-integrity sealing solutions for oil & gas, petrochemical, power generation and high-pressure pipeline systems. Our product range covers basic style, loose outer ring and integral outer ring Kammprofile gaskets, along with related spiral wound gaskets, ring joint gaskets and non-asbestos gaskets.
In the demanding world of industrial fluid and gas containment, achieving a reliable, leak-free seal under extreme pressure and temperature conditions is non-negotiable. Standard flat gaskets often fall short in these rigorous applications. This is where the specialized engineering of Kammprofile gaskets becomes essential. As a cornerstone of high-integrity sealing solutions, Kammprofile gaskets are engineered to create a superior metal-to-metal bite, providing exceptional sealing performance for flange connections in critical service environments.
At Kaxite Sealing, we leverage decades of metallurgical and engineering expertise to manufacture Kammprofile gaskets that meet the most stringent global standards. Our products are trusted in industries where failure is not an option, including oil and gas production, petrochemical refining, power generation, and high-pressure pipeline systems.
Kammprofile gaskets, often referred to as serrated metal gaskets or ring-type joints (RTJ) in specific profiles, are machined from solid metal rings. Their defining characteristic is a series of precisely machined concentric grooves or "serrations" on both the top and bottom sealing faces. These serrations create sharp, concentric ridges.
The sealing principle is mechanical and highly effective. When the flange bolts are torqued, the sharp ridges of the gasket bite into the softer material of the flange faces (or into a companion gasket). This plastic deformation creates multiple concentric rings of intimate metal-to-metal contact, forming a labyrinth-like seal that is exceptionally resistant to leakage of high-pressure gases or liquids.
Multiple concentric sealing lines provide a far more effective barrier against leakage compared to flat gaskets, especially for gases and light hydrocarbons.
Constructed from solid metal alloys, they withstand extreme pressures (often exceeding 10,000 psi) and temperatures from cryogenic ranges up to 1000°F (538°C) and beyond.
All-metal construction minimizes gasket relaxation that can occur with composite gaskets under sustained load and temperature cycling.
By selecting the appropriate alloy (e.g., Stainless Steel, Inconel, Monel), compatibility with a vast range of corrosive process media is achieved.
The performance of a serrated gasket is dictated by its material, dimensions, and serration profile. Kaxite Sealing offers a comprehensive range manufactured to exacting specifications.

Q: When should I use a Kammprofile gasket instead of a spiral wound or flat gasket?
A: Kammprofile gaskets are the optimal choice for high-pressure, high-temperature applications involving gases, light hydrocarbons, or hazardous fluids where absolute leak integrity is critical. They are preferred over spiral wound gaskets in services prone to rapid pressure fluctuations or fire scenarios, as they have no filler material to burn out.
Q: Can Kammprofile gaskets be used on standard raised face (RF) flanges?
A: Yes, concentric or spiral Kammprofile gaskets are specifically designed for use on flat face or raised face flanges. Flange surface finish is typically 125-250 µin Ra. For Ring Type Joint (RTJ) styles, matching RTJ grooved flanges per ASME B16.5 or API 6A specifications are required.
Q: What is the MOQ for wholesale Kammprofile gaskets from Kaxite Sealing?
A: Our standard MOQ is 50 pieces per gasket type for wholesale orders. For custom and OEM gaskets, MOQ may vary depending on material, dimensions and packaging requirements. Free samples are available for quality evaluation before bulk purchase.
Q: How long is the lead time for bulk Kammprofile gasket orders?
A: Standard lead time is 7-15 working days for most Kammprofile gasket products. Custom and OEM orders may require 15-25 working days depending on specifications and order quantity. Rush orders can be accommodated upon request. We ship worldwide via sea, air and express couriers.
Q: How do I determine the correct material grade for my application?
A: Material selection depends on three primary factors: the corrosive nature of the process fluid, the operating temperature, and the required mechanical strength. A Kaxite Sealing engineer can assist you with this critical selection. Generally, Soft Iron is used for non-corrosive hydrocarbons, 316 Stainless for general corrosion, and high-grade alloys like Inconel for chloride-rich or high-temperature environments.
Q: Do you offer custom-designed Kammprofile gaskets for non-standard flanges?
A: Absolutely. A significant part of our business at Kaxite Sealing is providing custom sealing solutions. We can manufacture Kammprofile gaskets to any required size, serration pattern, and material specification from customer-provided drawings or samples. Our advanced CNC machining ensures precision for even the most unique applications.
