This paper deals with the sealability of compressed fibers sheet gaskets (CFS) at room temperature for liquid and gas fluid. A method for measuring liquid leakage is proposed and the liquid leakage of CFS is measured. In addition, applying a conversion equation of leakage through aperture between gasket and flange to the results of room temperature tightness test (ROTT), the liquid leakage is calculated. The experimental results using CFS were ten times smaller than the calculated results concerning the variation in gasket stress and internal pressure. Therefore ROTT can't be applied to design of bolted flanged joints when liquid fluid is used. Accordingly, it is concluded that ROTT for liquid fluid must be measured.
