FIP Gasket

What are FIP Gaskets?

Form in place or FIP Gaskets are gaskets that are created on the part they are meant to seal.  Instead of sourcing the correct size and shape gasket for each seal, a semi liquid anaerobic sealant is dispensed onto the flange.  Care is taken to dispense around every opening to ensure a complete seal.  Thus the gasket is formed in place.  Gasketmakers, FIP Gaskets are anaerobic adhesives which cure only in contact with metal once air is excluded.  In other words once the two pieces of metal squish the sealant to the proper thickness, air is excluded air and the cure begins.  Excess can easily be wiped away.  FIP gaskets replace traditional cork, wood, rubber, paper, and silicone gaskets.

Why bother?

There is an infinite number of shapes and sizes one bottle of FIP gasket can create which eliminates the need to stock or source pre-cut gaskets. Other benefits of FIP gaskets include:

  • No long-term embrittlement
  • Easy to dismantle with normal tools
  • Seals rough surfaces; reduce machining needs
  • Non-shimming
  • 100% surface contact for uniform stress distribution
  • No relaxation or shrinkage eliminates need to retighten over time
  • One adhesive will replace many pre-cut gasket shapes
  • No need to handle fragile gaskets
  • No disintegration means no leaks or blockages
  • Vibration proof

 

Which fip gasket is best for my application?

FIP Gaskets are available in high and low strength.  Low strength is desired for ease of removal from soft metals such as aluminium and brass.  Although high strength grades can be removed using normal tools, low strength may be desired in applications where the fip gasket is removed frequently.  High strength and high temperature resistant grades are also available.  The thixotropic nature of many fip gaskets makes them easy to dispense but prevents flowing into undesired areas.
