                        "F"    
                          Face Seals - Rubber rings used like a gasket 
                          between two flat pieces of metal.    Failure 
                          Modes Analysis (FMA) - A formal, structured procedure 
                          used to analyze failure mode data from both current 
                          and prior processes to prevent occurrence of those failure 
                          modes in the future.     Fastener Seals 
                          - See Bonded Seals.    Feasibility - A 
                          determination that a process, design, procedure, or 
                          plan can be successfully accom- plished in the required 
                          time frame.     Fibre Seal Rings - Aa gasket 
                          or other die cut, water-jet cut or formed ring used 
                          to seal between two surfaces.    Filler 
                          - Any compounding material, usually in powder form, 
                          added to rubber in a substantial volume to improve quality 
                          or lower cost. The most important reinforcing filler 
                          is carbon black. The most important inert filler, diluent 
                          or extender is whiting.    Finish, Mold 
                          - The quality or appearance of the machined surface 
                          of a mold.     Finish, Product - The quality 
                          or appearance of the surface of a rubber product.   
                            Finite Element Analysis - A technique for 
                          modeling a complex structure. When the mathematical 
                          model is subjected to known loads, the displacement 
                          of the structure may be determined.     Flange 
                          Packings - A pipe flange gasket.    Flange 
                          Seals - A seal used on the bolt-up flange on a hydraulic 
                          systems - usually on the hose fitting or pipe flanges.  
                            Flash - Excess rubber on a molded product 
                          resulting from cavity overflow at the parting lines 
                          where the mold sections are separated.     Flex 
                          cracking - A cracking condition of the surface of 
                          rubber articles such as tires and footwear, resulting 
                          from constantly repeated bending or flexing in service. 
                              Flow Marks - Surface imper- fections 
                          due to improper flow and failure of stock to knit or 
                          blend with itself during the molding operation.   
                            Friction - Resistance to motion due to the 
                          contact of surfaces. |
