We manufacture cut flat gaskets which are intended to guarantee watertightness and sealing. We can offer you cut-to-size parts or parts according to DIN, ASA, ASME, API standards. Flat gaskets made of expanded PTFE are cut from 100% pure expanded PTFE sheets. We have our own cutting section which enables us to meet your requirements in the shortest possible time and at a competitive price.
The main function of this product is to ensure watertightness
PTFE offers excellent chemical resistance, pH0-14 (except for molten alkali metals and elemental fluorine), to oils, petrol, water, acids, etc
Flat gaskets made of expanded PTFE meet the food regulation CFR 21 FDA177.2600 and the EC 1935/2004 regulation. They also comply with REACH. They can therefore be used in food and pharmaceutical environments
Expanded PTFE is a soft and flexible material that adapts easily to irregular surfaces. It is ideal for use in sealing flanges that are damaged or have irregularities
Expanded PTFE has excellent pressure resistance
Expanded PTFE tolerates temperatures ranging from -240 and +260ºC with peaks up to 315ºC
The material is very soft, so its use is recommended in flanges with a risk of breaking under pressure due to its fragility (glass, ceramic)
Quality control of expanded PTFE flat gaskets
Thanks to these characteristics, flat gaskets made of expanded PTFE can be used for:
Permit the sealing of flanges used for oils, petrol, water, acids, etc
Enable sealing of smooth surfaces
Enable operation in heat exchange systems
Enable sealing of tanks
To allow sealing between flanges which are at risk of breaking due to brittleness and pressure
