Custom flange gaskets according to ČSN EN 1514 and ASME/ANSI. Flat, spiral, metal, RTJ rings and strips. For industry, energy, and chemistry.
These values are approximate and may be influenced by other factors. We will be happy to consult with our expert to make sure you make the right choice.
It solves the problems caused by insufficient elasticity of seals and prevents the leakage of pollutants into the environment. Suitable where cooling and re-heating of the flange occurs.
The metal sealing rings are designed for high pressures and temperatures - they can seal joints with pressures up to 1500 bar and temperatures up to 1000 °C.
Metal core seal combined with a soft sealing layer of graphite or PTFE. For use in high pressure and heat stressed flange joints.
It solves the problems caused by insufficient elasticity of the seal. Also suitable for applications with low initial tightening torque.
Metallic coated gaskets are produced in various combinations of metallic and non-metallic materials. Use in a wide range of industrial applications.
Self-adhesive flange tape made of multidirectionally oriented expanded PTFE.
Universal flange tape with self-adhesive layer of expanded, unidirectionally oriented PTFE.
Self-adhesive flange tape made of expanded unidirectional PTFE with higher specific gravity.
Self-adhesive tape made of expanded PTFE with higher specific gravity and stabilizing fillers.
Circular and oval seals are made of temperature resistant fabrics treated with elastomers. Suitable for various applications.
Thin knurled tape made of expanded graphite.
The reamer is designed for cutting seals from soft materials. It significantly increases the productivity of work while maintaining the required dimensions.
Due to its spherical shape and relatively small sealing area, the seal achieves a high specific pressure during installation and thus very good sealing properties.
The Teflon envelope ensures the chemical resistance of the classic sealing material. For the most demanding applications in the pharmaceutical, chemical and food industries.
Distribution of Klingerit is prohibited due to its dangerous asbestos content. We offer you modern alternatives.

Seal made of homogeneous flexible graphite film, coated on both sides with polymer film. Dimensions according to standards and to order.
Seal made of homogeneous film of multi-layer expanded graphite reinforced with a larger number of inserts. Very low oxidation value. For higher pressures and temperatures. Dimensions according to standards and to order.
Seal made of restructured 100% virgin PTFE reinforced with hollow glass microspheres. Suitable for brittle or damaged flanges. Dimensions to standards and to order.
Seal made of restructured 100% "virgin" PTFE reinforced with silica filler against cold creep. Suitable for high pressures and temperatures.
Seals made of restructured 100% "virgin" PTFE reinforced with selected inert fillers against cold creep. Suitable for steel and stainless steel flanges.
POWERflon BG-S seals are made of multidirectionally oriented expanded 100% PTFE. It only changes thickness under load.
Seal made of aramid fibre rubber plate with NBR binder. For low pressures and temperatures. Dimensions according to standards and to order.
Seals made of a fibre-rubber plate made of a mixture of aramid and cellulose fibres with NBR binder. For medium pressures and temperatures. Dimensions according to standards and to order.
Seals made from a fibre-rubber plate made from a mixture of aramid fibres with NBR binder. For medium to high pressures and temperatures. Dimensions according to standards and to order.
Seal made of aramid fibre rubber plates with CSM binder. Good chemical resistance, for various aggressive media. Dimensions according to standards and to order.
Graphite and carbon fibre fibre fibreboard seals with NBR bonding. For the highest pressures and temperatures. Dimensions according to standards and to order.
SBR is a cost-effective type of general purpose rubber. It has poorer resistance to atmospheric influences and chemicals.
NR rubber excels in its abrasion resistance and elasticity. It is not resistant to oil, ozone and atmospheric influences.
EPDM rubber is resistant to atmospheric influences, UV and ozone radiation. It has good temperature resistance.
Neoprene is primarily used in refrigeration and applications where the seal is exposed to the weather.
NBR is an oil-resistant rubber suitable for use primarily in mineral oil-based media applications.
Silicone is resistant to high temperatures, atmospheric influences and selected chemicals. Suitable for food applications.
Spiral seal with inner and outer ring in 316L stainless steel and graphite filling.
Spiral seal with 316L stainless steel inner ring, graphite filling and carbon steel outer ring.
DRS-2 rubber gasket made of NBR.
Rubber-metal seal DRS-2 made of EPDM with KTW, DVGW (drinking water) approval.
Flange gaskets are a key element of any piping system – their proper selection directly affects operational safety, emissions, and the efficiency of equipment. We offer a complete range from flat gaskets for standard flanges to demanding metal and semi-metal gaskets for extreme conditions. We manufacture to specifications according to ČSN EN 1514 and ASME/ANSI as well as custom production according to drawings or samples.
| Type of Gasket | Standard | Pressure Range | Typical Materials |
|---|---|---|---|
| Flat (IBC) | ČSN EN 1514-1 | PN 6–40 | PTFE, graphite, fiber rubber, rubber |
| Spiral Wound | ČSN EN 1514-2 | PN 10–160 | Stainless 316L + graphite/PTFE |
| Camprofile | ČSN EN 1514-4, -6 | PN 40–160 | Stainless + graphite/PTFE/mica |
| RTJ Rings | ASME B16.20, API 6A | High Pressure | Steel, stainless, Inconel |
| Metal Jacketed | ČSN EN 1514-7 | PN 10–64 | Stainless, copper, aluminum, Monel |
| Rubber-Metal | ČSN EN 1514-1 | PN 6–40 | NBR, EPDM + steel |
For pressure class PN 40 and above, we recommend switching to semi-metallic or metallic gaskets – spiral wound or camprofile. For extreme applications (PN 100 and above), RTJ rings or camprofile gaskets with a graphite layer are suitable.
RTJ (Ring Type Joint) is a metal ring gasket for high-pressure flanges in the oil and gas industry. It is used on flanges according to ASME B16.5 and API 6A where standard flat gaskets are insufficient – typically for pressures above 100 bar.
Yes. We cut flat flange gaskets according to drawings, samples, or specified dimensions from the customer. For spiral wound, camprofile, and RTJ gaskets, we manufacture according to standards or individual specifications. Contact us with your inquiry.
For aggressive media, we recommend PTFE gaskets or Teflon jackets (chemical resistance pH 1–14). For a combination of high temperatures and chemical resistance, camprofile gaskets with a PTFE layer or spiral wound gaskets with PTFE filling are suitable.
