Powerful
Sealing technology

Today, seals are used in extreme operating conditions and must seal permanently to ensure production processes are safe. Createc specializes in the production of high-quality seals and sealing systems made of composite materials.

The right sealing solution for your application.

O-ring, spring-elastic PTFE seal or metal C-ring. Increasing safety and quality requirements for processes and production equipment, as well as steadily growing cost pressure, determine everyday life in many production plants. As a market-leading and internationally active company, we specialize in the manufacture of high-quality seals and sealing systems made of innovative composite materials and offer you individual solutions for your sealing application. Many users rely on elastomers as sealing materials for their seals. Particularly important is the resistance of the seals to high pressures and high and low temperatures. In addition to our CREAFLEX® O-ring range, we also offer CREAFLON® spring-elastic PTFE seals and CREALLOY® metal seals as C-rings.

Creaflex®

createc-creaflex-o-ring-yellow-teaser
CREAFLEX® O-ring seals for high chemical loads.
CREAFLEX® perfluoroelastomers offer universal chemical resistance - even in the most aggressive pumped media - and are reliable for high pressure and high temperature applications. The sealing systems meet the strict standards of purity and traceability of the materials used and have full FDA approval for perfluoroelastomers 21 CFR 177.2400 (d1); (d2).

CREAFLEX® elastomers for high-temperature applications.
For many applications, it is particularly important that the seal is heat-resistant. CREAFLEX® HT elastomers have a temperature resistance of up to +280°C. Leading manufacturers of pumps and valves have already successfully used CREAFLEX® HT elastomers.
createc-creaflex-o-ring-blue-teaser
CREAFLEX® elastomers for low-temperature applications.
CREAFLEX® LT elastomers exhibit extremely high temperature resistance down to -60°C, even with aggressive media. The performance and service life of valves, pumps and mechanical seals are significantly increased by the use of CREAFLEX® LT elastomers.
createc-creaflex-o-ring-black-teaser
CREAFLEX® elastomers resistant to explosive decompression.
In the oil and gas industry, extraordinary stresses are placed on the sealing material. Here, seals must function reliably with critical gases and at high pressures of up to 400 bar. When pressure is released quickly, conventional elastomer seals can be damaged by "explosive decompression". CREAFLEX® high-tech elastomers meet these extreme requirements safely and reliably and make a major contribution to the process reliability of the production plant.

CREAFLEX® food grade elastomers with FDA compliance.
Createc is one of the few seal and O-ring manufacturers to have FDA compliance for all its elastomer materials FFKM, FEPM, FKM, EPDM as well as HNBR. The CREAFLEX® FFKM extraction data also meet the stringent FDA registration requirements for perfluoroelastomers according to CFR177.2400 (d1) and (d2). In some cases, the composites very significantly undercut the limits required by FDA approval.

Crealloy

Creaflon®

createc-creaflon-asiv-teaser
CREAFLON® spring-elastic PTFE seals for extreme applications.
CREAFLON® spring-elastic PTFE seals made of polytetrafluoroethylene are characterized by universal resistance to most media compared to all other plastics and elastomers.
createc-creaflon-asoc-teaser
The operating principle of CREAFLON® spring-elastic PTFE seals.
CREAFLON® PTFE seals are spring-reinforced grooved rings that generate sealing action through spring preload and the applied pressure. When pressure is applied, the sealing effect is increased in proportion to the pressure.
createc-creaflon-rsv-teaser
CREAFLON® spring-elastic PTFE seals are particularly versatile.
The CREAFLON® spring-elastic PTFE seal impresses with chemical resistance to almost all media, low wear, low coefficient of friction, a pressure application range of up to 4,000 bar, a temperature application range of -200°C to +300°C, steam sterilizability and long service life.

Crealloy®

createc-crealloy-ci-teaser
CREALLOY® metal gaskets for extreme temperatures.

CREALLOY® metal seals are perfect for use in the temperature range from -250°C to +650°C, for required long service lives, for high radiation exposure and wherever very low leak rates are required. CREALLOY® metal seals are seals that are used in force shunt.

createc-crealloy-cse-teaser
The operating principle of CREALLOY® metal gaskets.

The CREALLOY® metal gasket is a C-shaped gasket made of metal with a soft coating. When pressure is applied to the CREALLOY® metal gaskets, the sealing effect is increased in proportion to the pressure. CREALLOY® metal gaskets can be used as static and dynamic seals.

Tough: The material properties.

CREALLOY® metal seals are available as axial seals as well as radial seals. Compared to other seals, they have the lowest leakage rate up to 10-⁹ ml/s, withstand a pressure range up to 5,000 bar. Due to the elastic recovery, deformations of the sealing surfaces can be compensated.
