  • ANSI ASA Flanges
    MDC ASA-style flanges mate with standard 150 lb. ASA-ANSI flanges. Flanges are offered with choice of smooth face or O-ring groove. Eight flange sizes are detailed in this section. They are available blank or bored to fit tube sizes 1-1/2" through 12" O.D.

In racing, a split second can make the difference between winning and losing, or between a serious accident and a trouble-free ride. That's why race teams in CART, Formula 1, Indy Car, and NASCAR
  • Understanding Tolerance Stack-up
    an effective seal. The combination of these tolerances is the tolerance stack-up. The graph above shows a situation where the O-ring cross section tolerance is +-0.003 ", the groove diameter tolerance is +-0.002 ", and the bore diameter tolerance is +-0.001 ". In this example the metal dimensions can
  • Odd-Shaped Seal Stops Random Leaks
    O-ring, exerts a positive retaining force in the O-ring face seal (ORFS) fitting groove that prevents it from falling out or getting pinched in the connection. Compared with conventional O-rings, Trap-Seal has a larger overlap between the

  • CR4 - Thread: How to select and design an O-Ring?
    I have found the Parker O-ring Handbook to be helpful in spec -ing O - ring size/materials and O-ring groove dimensions.
  • Non-Image-Forming Optical Components
    Mechanically, the window is secured into a stainless steel cell with a torqued threaded retaining ring (also made of stainless) and sealed with a MIL - spec elastomeric sealant. The cell is provided with a mounting flange that is grooved to accept an O -ring as indi- cated in the detail view.
