What material (elastomer) to be used for gasket ?
  • Silicone: Platinum cured silicone is the material of choice in sanitary water systems when PTFE is not feasible due to severely misaligned fittings, or if the cost of high pressure clamps does not outweigh the benefits of PTFE (extended service life).
  • FKM, Fluorosilicone and EPDM compounds are specified by many of our process equipment manufacturers. They are generally suitable for these applications, however, service life must be considered and a preventative maintenance program be implemented to mitigate degradation. They are not recommended for continuous use in SIP procedures.
  • PTFE is the material of choice whenever low temperature flexibility or hygienic seal memory is not required (not recommended where large temperature variations occur frequently, leakage can occur).
If you require door seal for your autoclavable or sterilizer, please provide us with the following information:
  • If possible, a sample of the TC gasket required.
  • A dimensional drawing showing the gasket you require (including Elastomer,Type, ID, OD, Bead Center & Bead Outside ).
  • Quantity required.

Sevitsil is offering flange gasket and has been delivering thousands of custom gaskets and custom washers to almost every industry to meet or exceed each customer’s most stringent requirements.

A Silicone flange gasket is used to join or fit between two sections of pipe, each pipe section typically has a flared or flattened area that provides a surface for the gasket to attach. Our standard available sizes are suitable to ANSI 150# and 300#.

Types Of Flange Gaskets
  • Ring gaskets: A ring gasket is a gasket with an inner diameter (ID), outer diameter (OD) and Thickness.
  • Full face gaskets: A full face flange gasket is similar to a ring gasket with bolt holes (aligned in a bolt circle) in the surface area between the ID, OD and Thickness.
  • Sevitsil can custom manufacture and fabricate flange gaskets, ring gaskets, man way gaskets and full face gaskets in a variety of materials
