- - - - Too high
        
        Gasket squashes
        
        Flanges bend
        
        Bolts break
        
        Leak
      - Too little
        
        Gasket blows out
        
        Leak
      - Gasket
        
        Soft enough
        
        Deform and create seal
        
        Hard enough
        
        Not to overcompress
      - Factors
        
        Size
        
        Grade
        
        Number

        Torque dependent on gasket and bolts
    - - Squash gasket into flange imperfections
      - To squash the gasket we tighten the bolts on the flange
    - - Spring
        
        the more stretch the more force pushing back
        
        stretch a spring and it tries desperately to return to its original length
        
        bolt is a spring
        
        quite complex and books written on subject
      - Torque
        
        Bolts work in the saw way
        
        To stretch the bolt we use a nut
        
        the more we turn the nut, the more the bolt stretches and the more it wants to return
        
        this elastic force forces the flanges together and compresses the gasket
        
        nut travels down thread of bolt until it hits the flange
        
        the bolt begins to stretch as nut cant travel down any further
- - - - Soft
      - Can be cut
    - - Medium
      - Can (sometimes) be partially cut
    - - Hard
      - Can't be cut
