*1: PKA-04 to 14 values are for pneumatic pressure of 0.05 to 0.7 MPa, and PKA-20 values are for pneumatic pressure of 0.05 to 0.5 MPa. With 0.05 MPa or less pressure, the seal will be unstable.
*2: The conversion between the effective cross-sectional area S and the sonic conductance C is S ≈ 5.0 × C.
