Reseal Pressure and Leakage

N/A Cracking Pressure Tolerance: ±5%

Flow at cracking pressure:

  • Gas = 5cc/min
  • Teflon® seals = 0.02 scfm

    Reseal pressure
    Crack Pressure Reseal Pressures
    400-599 psi 80% of C.P.
    600-899 psi 85% of C.P.
    900-5999 psi 90% of C.P.
    6000 psi & greater 95% of C.P.

    Leakage at reseal pressure

    Gas Ascending pressure = zero to 95% of cracking pressure
      Descending pressure = zero at reseal 
    Liquid Ascending pressure = 5cc/min maximum to 95% of cracking pressure
     

    Descending pressure = 15cc/min maximum at reseal
