ISO-KF System

🔹 Short Half Flange
Corevac Short Half Flange is a practical and high-precision flange component designed for compact connection points.
It is especially preferred in laboratory systems, portable pumps, and vacuum lines where space is limited.
Each piece is machined with precision on CNC systems; the smooth surface finish ensures excellent sealing and repeatable assembly performance.
All Short Half Flanges are manufactured from 304 or 316L stainless steel according to Corevac production standards and fully comply with ISO-KF norms.
Its compact structure shortens installation time and provides flexibility in connection design.

Corevac engineering creates high reliability even in the smallest details — because in vacuum systems, even the slightest leak makes a difference.

🔹 Long Half Flange
Corevac Long Half Flange provides a larger bonding area in welding and adapter applications, creating a secure vacuum line.
Its extended weld length and added rigidity provide superior durability against vibration, thermal expansion, and mechanical stress.
Digital calibration CNC systems used in Corevac production lines maintain dimensional consistency; therefore, every Long Half Flange maintains its sealing performance even after hundreds of reassemblies.
This component fits perfectly into large-scale process systems, pump lines, and experimental research platforms.

Corevac Long Half Flange — the strong representative of reliable weld points.

🔹 Full Flange
Corevac Full Flange is a complete surrounding flange solution that provides maximum sealing area and direct connection in ISO-KF systems.
Its wide surface contact withstands high compression forces and ensures optimal pressure distribution on the O-ring sealing surface.
These flanges perform exceptionally well in high-vacuum (HV) and ultra-high-vacuum (UHV) environments.
Manufactured in 304L or 316L stainless steel with an optional electropolished finish, the surface roughness is minimized, reducing gas entrapment.
The Corevac Full Flange series is designed for engineering projects seeking long-term durability and international compatibility.

Corevac Full Flange — the strong, leak-tight foundation of high vacuum.

🔹 Blanking Flange
Corevac Blanking Flange safely closes unused line ends and protects the system against environmental factors.
It is the ideal solution to maintain line integrity during testing, maintenance, or deactivation phases.
Its stainless-steel body and high-quality surface provide perfect contact with the gasket.
Every Blanking Flange is vacuum-leak tested, ensuring stable performance even after repeated use.
Corevac also offers custom-marked and perforated blind flange options, making process-line management easier.

“Stopping a line is not enough — protecting it safely is what matters.”
This is the Corevac engineering approach.

🔹 Weld Ring Flange
Corevac Weld Ring Flange is designed for permanent connections and high-strength vacuum systems.
Its large welding surface provides excellent resistance to mechanical vibration, high temperature, and pressure.
The post-weld geometry minimizes deformation and supports long-lasting operation of sealing elements.
This flange type is ideal for high-temperature process lines, plasma systems, and industrial vacuum installations.
Every flange undergoes laser-based symmetry and surface-quality testing within Corevac’s production process.

🔹 Seal (Inner-Centered)
Corevac Inner-Centered Seal is an inner-guided sealing solution that provides maximum centering accuracy in small-diameter systems.
Its special channel design ensures the O-ring fits perfectly and prevents displacement during assembly.
Manufactured from FKM, NBR, or silicone, these seals can operate safely between −50°C and +200°C.
Corevac’s ISO-KF seal series offers long-term performance thanks to low-permeability elastomer compounds.
All seals are packaged in clean-room conditions and delivered with certified particle-free surfaces.

Corevac Seal — flawless sealing for systems where every micron matters.

🔹 Seal (Outer-Centered)
Corevac Outer-Centered Seal provides installation convenience and stable alignment in large-diameter flanges.
Its outer-guided structure balances the weight of connection components and ensures optimal compression force on the sealing surface.
Preferred in high-vacuum applications, this seal maintains form stability during temperature cycles thanks to Corevac’s special elastomer formulation.
Outer-centered seals are used widely in laboratory lines as well as industrial process systems.

Even in large systems, small details make the difference — and Corevac engineering makes that difference real.

🔹 Casting Clamp
Corevac Casting Clamp provides fast, secure, and balanced connection between two ISO-KF flanges.
Its cast structure distributes clamping force evenly, eliminating gasket deformation risk.
Available in aluminum or stainless-steel versions, each clamp is tested according to Corevac torque standards.
The ergonomic clamp design provides one-hand installation convenience and reduces time during maintenance operations.
Its corrosion-resistant surface coating maintains both durability and a clean appearance even during long-term use.

Corevac Casting Clamp — secure tightening, easy maintenance, long life.
