Seals for the Chemical Industry


Meadex supplies Viton FKM moulded seals for the chemical Industry. Seals designed for aggressive chemical and pressure systems.
This requires technical resource for materials and validation of the final component. This may require testing for automated Visual inspection.
Also clear understanding of the sealing criterial and customer performance expectations and working environments. Meadex offers simply O-rings to complex moulded seals in high value elastomers such as FFKM.


Customers often ask, ” what is the service life of this seal ?” This is a difficult question to answer and depends on a number of factors, such as the type of fluid or chemical it is sealing against; the temperature of the service environment; whether the seal is static or under dynamic flex conditions; the sealing pressures involved; and most importantly- the attention and care given during the installation and flange tightening procedure.
The degree of compression necessary to achieve a leak free seal is dependent on the internal pressure and temperature of the fluid stream; the parallelism of the flange surfaces; the design of the seal area (machined groove, perimeter backing ring; or smooth flange); and the composition of the flange and piping (metal or resin/fibreglass). For most seal applications, a maximum deflection in the gasket thickness of 25% is recommended.
