PURPOSE:For keeping up the secure sealing of a very small amount of sealing material for a long period of time, to cure said liquid sealing material filled in the leaking clearance of screw joint sections from the porous material impregnated with said liquid sealing material. CONSTITUTION:A thread-like porous material 4 is wound with several turns round the whole circumferences of both the end face of an outer fitting side conduit 3a and the outer surface of an inner fitting side conduit 3b at the portion whisere a clearance 2 exists of screw joint section 1. Next, said sealing porous material L filled in said clearance 2 through the capillary action thereof from said material impregnated therewith and kept therein until curing. Thereby, leakage can be stopped with a very small amount of said sealing material L. Further, said sealing material L filled in said clearance 2 on one hand and conduits 3a and 3b on the other become difficult to separate from each other through the former's curing. Thus, secure sealing can be kept up for a long period of time. |
